- New feature: shift+ctrl+t in Mesh editmode splits quads in exact opposite

way. Requested for low-poly modeling.

- fix: on exit editmode, the code always created a mesh->dvert block...
  silly, this made other code confused which decided whether to use
  dverts (vertex groups) or not.

- removed obsolete call from armature.c. Also fixed name of function there,
  preparation work for nicer support in Blender for "deform envelopes"
