Third round of override macro updates. Should have touched all functions stating virtual for now. This might still have missed some, as sometimes the virtual keyword is missing on derived functions. And some open points are also still under consideration, will be fixed in future.

Fix syntax problems in Cg renderer base classes, which came from the override changes. Not yet tested, but should compile again.

git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@4546 dfc29bdd-3216-0410-991c-e03cc46cb475

Exposed some more functions:
getArchiveName returning name (path) of archive
getColor and getColorHSL for color select dialog
get/setDoubleClickTime in device for setting the time offset necessary to have two separate clicks instead of a double-click

Removed deprecated getXJoint and getMS3DJoint functions

Some fixes:
Added get/setCurrentRenderPass to scene manager (internally renamed, exposed)
Removed destructor from light scene node.
Removed getType calls from archive loaders (one file archives have this)
Removed some internal exposures and virtual attributes for protected classes

Add override patch by hende, to check for proper deriving in the class tree. Added MSVC support for this feature, should work beginning with MSVC 2010

Another try to fix the compilation issues. Still untested, as my MSVC is currently out of business...

- revert rotation patch from rev4478. Texture Matrix will be default solution for manipulate 2d image drawing.

- Added support for rotation 2D images. This patch base on FuzzYspo0N patch from irrEXT. (Software drivers aren't supported).

git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@4478 dfc29bdd-3216-0410-991c-e03cc46cb475

New method for camera scene nodes. updateMatrices updates the camera matrices without uploading them to the driver directly. Patch submitted by hendu

Added window position parameter to device creation params. For now, window is not programmatically movable. This patch is merely intended for restoring the device in the same location as with last run. Patch provided by Auria

git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@4472 dfc29bdd-3216-0410-991c-e03cc46cb475

Added hendu's constification patch for memory read/write files. Also slightly changed the use of global C methods to class specific static methods, which seems more appropriate
