-> Bevel

Fixed the following problems with Bevel code

-meshes with 2 edged faces left over at the end would cause buffer
overrun whens converting from a Bmesh to a Derived Mesh. The
conversion process now checks for both double edges and faces
and removes them when present.

-BME_reverse_loop euler had a bug that was causing the corruption of
radial cycle. This would lead to the bevel tool hanging for a long time
and possibly crashing.

-Added optimization of BME_reverse loop so that it no longer does tiny
allocations but instead uses an area of 'scratch' memory. The same thing
will be done to the Make Face euler soon

-Added proper call to selection flushing for editmode.

-Some miscellaneous cleanups and removal of unneeded debug printfs.
