Modifiers: Add Bone option for Texture Mask Object

This patch adds the option to use an armature bone in place of an object for texture mask coordinates.

This affects the 3 vertex weight modifiers, the displace modifier, the warp modifier, and the wave modifier.

With minor changes from Bastien Montagne (@mont29).
