Title: Changed regex to support morph animations exported from blender

Very minor change in the regex pattern. Animations exported through the Three.js Blender plugin use an underscore between the frame and the name of the animation:

Animation_0000001
Animation_0000002
Animation_0000003

etc.

This is also present in the current release in the parseAnimation function of the MorphBlendMesh.js
