A3DGE Code

+ Added class EStateMachine.
* TColorDescription moved to a3dge.material.
* Improved material subsystem. Now materials can own its texture and material
lists can own or not the materials.
* As a side effect of the previous, rendering should be a tad faster now.
+ Added routines to load Material Libraries (mtl files).
+ Added directory ~/trunk/bin/tool forgotten in previous commits (Duh!).
* Documentation fixes and updates.
