Particles

=========

- Fix for bug #7840: adding particle system to nurbs, curves crashes.
  Now simply doesn't allow to add a particle system to a non-mesh
  object, the current code does not support it.
- Fix for bug #7834: deleting vertices of an object with a particle
  system crashes. Fixed by disabling particle display for objects in
  editmode.
- Fix for the particle add brush on subsurfed objects.
