code cleanup: move bmesh inline funcs to headers (avoids compiling the C files).

code cleanup: bmesh_ source files in our editor dir, they are the same as other editmesh_ files.

remove bmesh_selecthistory.c, only wrapped a few functions.

fix for error with saving files after double clicking, the 'need_active' setting was getting saved which caused save to fail when not caused by double click afterwards.

code cleanup: more consistent naming for mesh operator functions.

Sequence Editor Themes:
