Shadow system refactoring.

- Basic and PSSM shadow renderer are now deprecated
- There is now one processor and its filter conterpart for each light type
- created an abstract shadow processor that hold the common shadowing code. It's totally independent of the shadow technique used.
- extracted the CompareMode and FilterMode enum to their own files.
- renamed FilterMode enum to EdgeFilteringMode
- refactored the shader code, to avoid duplicate code. all shadow related code is now gathered into Shadows.glsllib and Shadows15.glsllib.
- added spot light Shadows
- removed the ShadowCamera class as it was not used.
- removed "pssm" in the naming of classes, shader and shader libs since it's not relevant anymore
