Completo.blend edited, Completo.blend1/2, gun_gimp.xcf,
gun_image.png and gun_layout.png created for issue #180:

 - Completo.blend edited, UV map of the gun modified to be easier to make
   a texture.
 - Completo.blend1/2 left just in case.
 - gun_image.png contains the a bake of the gun, gun_layout.png contains
   the UV map itself(just an image) and gun_gimp.xcf is the texture I'm
   working with.
Completo.blend/1/2 and gun_gimp.xcf edited, gun_gimp.png created for
issue #180:

 - Basically: I did the new texture, gun_gimp.png.
