-> Bevel tools and Bmesh kernel

The following is a commit of Levi Schooley's bevel code and 
the bmesh library it depends on. The current editmode bevel has 
been replaced with a new per edge bevel function. Vertex beveling is 
also availible.

To set weights for the modifier to use, use the ctrl-shift-e shortcut on either edges 
or vertices.

Recursive beveling is turned of for the time being.
