Support Maven/Gradle artifact

[gjroelofs]

I would like to request support of a Maven/Gradle artifact that allows access to the conversion API through Java.

Use case:
In an effort to make our asset pipeline easier to work with, I'd like to add in a G3dXLoader to our project that tries to loads both FBX and G3DX formats. If a FBX file is supplied, it's hash will be checked against the converted G3D* file (if it exists) and if it doesn't match or exist, is auto-converted to the appropriate format.
