* Moved directories PythonScript and Lib from RexParts/RexPython/Resources/ to ScriptEngines/
* Added a line to prebuild.xml so PythonScript and Lib directories are copied to bin/ScriptEngines/ on build if they are newer.
* Removed old readme.txt from RexParts/RexPython/Resources

python's rexPlayMeshAnimation changed to have the same number of params as before. Added comment to samplemeshanim about what it tests.

python rexPlayFlashAnimationByUUID fixed (wrong number of params)

* Refactored RexClientView to RexClientViewBase and RexClientViewLegacy.
* Moved Skype releated stuff from IRexClientCore and RexClientViewBase to RexClientViewLegacy.

Added startup event tests.

Added volume collision to Python module. This uses the same volume collision that LSL also uses.

A bit of cleanup:
* Moved ModrexAppearance, ModrexFacialExpression and SitModule to RexParts/Modules.
* Removed outdated readme file
* Removed ModrexSuperobjects stub

* Make realXtend UDP ports configurable.
* Add new configuration option "FirstPort" under [realXtend]. Default value 7000.
* VoiceServers "voice_server_url" configuration is now under [realXtend]
* Python modules "rex_python" configuration is now under [realXtend]

Removed RexWalkDisabled and RexFlyDisabled from IRexClientCore and all references to them.
Modified Python script engine to use ScenePresence.ForceFly and ScenePresence.FlyDisabled instead.
This fixes bugs [#143] and [#144].

*Removed MovementSpeedModifier from IRexClientCore
*Removed all references to IRexClientCore.RexMovementSpeedMod
*Modified RexScriptInterface to use ScenePresence.SpeedModifier instead of the one in IRexClientCore

Added avatar movement speed test script

* Added new region module: SitModule. This module makes possible to enable or disable sitting of the clients from python module or region module. Possibly even from MRM.
* Removed old sit references from IRexClientCore and RexClientView

Sample script to test sit disabled feature

Fixed the login bug where SessionID was not valid.
Fixed the bug where Python module would not start because it didn't find the dot net script engine.

Added more avatar function tests and bot function tests.

Fixed to build since broken after revision 8907 or so.

Cleaned some log messages. Modified SPSetRot to update rotation in server also, not just send info to client.

Added some avatar function tests. Modified script function tests to use log4net.

Added new tests to test functionality of python script engine.

Added new tests to test more of the API functionality.

Added some python module test scripts.

Fixed few python module methods. GetSceneObjectPart was not acting as reliable as should have in some cases. Changed some of those to Entities.TryGetValue.

* Refactored client interfaces.
* Modified how modules identify clients

IRexClientAPI added to be used as base for both rexhumans and rexbots

more exceptions to log messages in scripting

Added samplemediaurl test script to Python module. Refactored rexSetTextureMediaURL from rxlslobject to rxactor like other methods are already.

This fixes rexPlayMeshAnimation function for python module.

- rexraycast fixed, see sampleraycast.py for sample how to use it
- lsl script functions returning string fixed to work in python

Fixed console command registration.
Removed OpenSim.Region.Environment.dll reference from prebuild.xml

* Added the missing mapping file
* Added the SQLiteDialect for RexAssetData. Thanks Paul Fishwick.
* Changed the python console command back to use. Now uses the new implementation of ConsoleBase

- own interface classes for adding collisionmeshes and other physics stuff
- removed references to ode
- cleaned up prebuild, added coremodule

Changed the OpenSim.Region.Environment namespace to OpenSim.Region.Framework as it was changed in new OpenSim.

rexobjectpropertiescache: objects are loaded into memory, saved & sent over the network only when necessary. Also other changes which clean up the prop handling much.

Added libs, RXCore and samples for Python module. See readme.txt for usage.

rexmod side of the ode physics changes
some rexclientview cleanup 

*Added first implementation of SpawnActor to Python module.
*Removed bin/Debug folder and project files. You should not commit these. Use runprebuild script to create project and solution files.

*Modified OnPythonClassChange a bit. Now Python module knows when script has changed. No proper cache yet though.

*Added OnPythonClassChange event to detect when Python script is initialized
*Added methods to Load and Save objects from outside ModrexObjects.
*Removed RexObjectPart and RexObjectGroup, which are not used anymore.

Merged branch to trunk. Note this patch requires OpenSim patch (http://opensimulator.org/mantis/view.php?id=3012) to be applied.

Fixed to match newest simulator.

* Added few new scripting features which were introduce after 0.4 release (Sit Disable & Vertical Movement Modifier).
* Implemented SendRexFog
* Implemented SendRexWaterHeight
* Added missing register cmd line that was accidentally in revision 18.

Added OnChangePythonClass event to RexObjectPart
Added SurfaceTouchEventArgs to touch_start event to get module to compile with newer opensim revision.

*Re-Implemented OnRexScriptListen
*Changed log messages to use log4net properly.

Fixed the PythonScriptCommand. Only 5 more events to go.

*Added few new Client properties and method stubs
*Fixed an error where client could not login. RexAuthUrl contained whole account info (user@domain). This will need a better fix.
*Modified RexPython module so it can boot itself up. This needs user to place Lib- and PythonScript-folders to bin/ScriptEngines. Most of the old scripts won't work at this time. For example "OpenSim.Region.ScriptEngine.Common" need to be renamed something differently.
*Added a couple event handles to RexScriptEngine to handle two RexClientView events.

Fixed a bit so ScriptEngine won't crash if the module can't be loaded properly.

Initial RexPython work. Changed code so it compiles, but many functions still not implemented. Needs still lots of work.

* Updating to latest
* Warning: Contains bugs.
