Saturday morning first cup of coffee hack (yeah, its a late

morning)

 - fun for the whole family, boolean mesh modifier... doesn't work
   with layered modifiers yet (just uses base mesh), although may
   god have mercy on your soul if you want to run boolean on a
   subsurf anyway
 - added displistmesh_add_edges

This exposes a bug in boolean, apparently the output is somehow
random (hash on alloc'd pointer value perhaps) which is sortof
lame.

It also makes more apparent the desire for some level of control
over dep graph evaluation during editmode (at the moment dep
graph is reevaluated for a mesh object in editmode, but since
mesh changes are on editmesh other objects don't really see
any change, so it is a wasted recalc).
