Subject: 2.5 - AnimData fixes

* Made AnimData blocks be stored as pointer instead of directly in the ID-datablock, so that fewer files will need to be recompiled everytime some animation settings change.

* Tried to fix some of the compiler errors that pop up in Yafray code. If this commit doesn't fix it, just disable Yafray code for now (WITH_BF_YAFRAY=0 for scons)...
