Fixed misplaced texture files, the armor textures should show up now.

Updated to model with armor bodygroups and working hitboxes

Updated playermodel lua list to hopefully prevent possible conflict with TFA GITS playermodel list.
I suspect the conflict was the .lua file being the same name, forcing gmod to choose one or the other and usually choosing the original GITS lua file that doesn't have the Elizabeth playermodel entry.
Lua file's name has been changed.

Initial addon creation.
