- bug fix, face center drawing was wrong for editmesh

Browse Source 
- added several useful utility functions to editmesh,
   these can simplify/clarify a lot of mesh code, check them
   out
 - cleaned up EdgeSlide a bit to be clearer/shorter
     o bug fix, EdgeSlide did not always cancel correctly
     o bug fix, EdgeSlide did not choose initial "control" edge
       correctly after calc_meshverts_ext change
