No mhx export option in unstable build

[WFab]

Blender closes when I import collada, with or without rig. I tried fbx too, both binary and ascii. Mhx2 is the only one so far (apart from obj) that imports without problems in blender (2.74). I'm going to try the new default rig in a few minutes.

Nope! Default rig didn't work either!
