Enable test for projection matrix. I have removed the projection matrix tweak from OpenGL driver, as it does not seem to have any effect. At least no good one.

Fix bug which showed up when RTT and text were used in the same scene. I have removed the old RTT checks in 2d methods, and placed a global fix for the texture matrix into the 2d mode setting.

Add driver attribute element for AntiAliasing level. This allows to check whether the driver has AA enabled, and which level.
Fix AA setup for OpenGL under windows, where the extension was missing and no error came up due to unsupported feature request. Now, the driver recognizes the missing support and properly sets AA to 0.

Fix the text scene node placing in viewports. The problem was, that the calculation took the absolute viewport dimension into account, while rendering into the viewport requires the screenwidth to be taken. Hence, the text was usually misplaced. The collision method can still be used for this mixed mode calculation (get screen coordinate during viewport rendering, use it for full screen rendering), but requires an additional parameter.
Software drivers don't support 2d rendering into viewports, so they still fail to properly position text (or other 2d things) into a viewport.

Patch by Auria, which allows to render text in gui static text elements over the element clip area. This makes handling of changing text simpler. As default, this feature is turned off.

Change addShadowVolumeSceneNode to replace the current shadow completely. This allows to change the shadow parameters, such that a call to addShadowVolumeSceneNode will always result in the correct shadow. Note that redundant calls to this method will be quite expensive now, so avoid them.

Note: Currently we still will have the font-texture for CGUIFont's in the cache afterward.
But that needs a more general mechanims that allows cleaning up textures easier when the last one has been removed.

ITriangleSelector::getSceneNodeForTriangle, ISceneNodeAnimatorCollisionResponse::getCollisionNode, ISceneCollisionManager::getCollisionPoint and ISceneCollisionManager::getCollisionResultPosition.
As collision functions often are followed by changing node positions users where so far forced to using const_casts (found by Greenya).
(This will lead once more to many post about correct getCollisionResultPosition usage, but can't be helped - those consts were too restricitive, sorry)

- Compile-defines can now be disabled from Makefiles/Projectfiles instead of having to change IrrCompileConfig.h each time (that's mostly to make it easier to use identical sources for client&server versions by simply using 2 different projectfiles)
- Disabled Xcursor support by default to avoid the additional link dependency on Xcursor lib (too many people got confused by that already).
