UV Map export combines multiple textures. #131

I currently have an entity model which has two separate texture images.
I have set up my UVs and went to export, but realized the VSMC is only capable of exporting a single UV image, resulting in a combination of the two maps layered on top one another.

Two textures and their UV maps in the VSMC preview:

Resulting combined export:

Hiding a shape/cube in the tree removes its UV from the preview, but is still exported, so as a workaround, I am going through and manually disabling each face on one texture, exporting, then repeating the process for the other.

Possible solutions I can think of would be allowing the user to select a texture and export only the associated UV map, and to make it so that shapes hidden in the tree have their faces excluded from the UV map export.
