boneweight copy-
fixed the "No X Crossing option "Made 0-x verts snap to eachother. Added mesh_mirror_tool This is a tool that makes verts mirror, so that you can use xmirror in editmode and weight painting. Have imported a heap of models that are made mirrored but are slightly out of being in the range that blender uses to be mirrored. So this means I can make a models verts snap to its mirrored locations. Options are Limit, Mode l>R, R>L or Middle, Normal Weigting, only mirror Same edge user count may add support for mirroring vert weights later.
