- Depricated another bunch of globals; all the totobj,
totmesh, totvert, and so on.
- All code that needs such totals now count it themselves,
these stats were not supposed to be reliable
- Editmesh now stores and manages own totals.
- Todo: make a scene->stats that tracks notifiers.
Bugfix: selecting failed in editmesh, backbuffer stuff was
too late, already using index ranges before it was set.
