Removed legacy formats for the marine files and added the up to date blender files to go with them.

Includes:
- marine_anims_all.blend  (model with all available animations)
- marine_anims_core.blend (model with t-pose, idle, walk, run)
- marine_anims_single.blend (model with only t-pose)
- marine_ik.blend.blend (model with custom IK skeleton, ideal for creating new animations)

Fixed lighting in the example and switched over to the new marine file.
