Blender Git Loki

removed doc_browser.py - since it covers ~half the BPY api, not documenting any of blenders data types.
replaced with a help_bpy_api.py, that opens a web browser at the Blender Python API page.
Camera.c - added a veriable .angle to camera, same as .lens but adjusts the camera angle in degrees (like the D button)
export_fbx.py - use the the camera angle property.
object_cookie_cutter.py - use PointInTriangle2D rather then own function.
buttons_shading.c - added OB: and tooltip to object world mapping.
interface_draw.c - (Simple theme) text buttons looked exactly like normal buttons (more confusing when they had no text), made the text and ID buttons render inset so you can tell them apart.
