Using a bit more flexible way to handle those values (range now from 10^-18 (20) to 10^2 (0) frames). Not sure we shouldn't rather get rid of such "magic" value and let user set frame threshold directly, though!

use diffuse alpha channel if no other alpha channel set, hidden option to treat all alpa as decals (no shadow and z offset)

- binary fbx files only
- version 7.1 or newer
- meshes, uvs, materials, textures
- support for blender-internal and cycles materials (depends on engine selected)

note - yes, this cant load fbx files exported by blender, for that to work we would need to update the exporter.

make addons blender versions consistent
