Various stuff in one commit;

- Added (BKE_utildefines.h) POINTER_TO_INT(poin) and INT_TO_POINTER(int)
  defines, to help fixing issues with switch to 64 bits systems. This
  assumes that a) not more than 16GB mem is used and b) that address
  space is below the 1<<35 value. The latter has to be confirmed, but it
  seems to conform the current 64 bits generation of OSs (for mallocs).

  Needless to say; use long if you want to store pointers! This is for
  temporal fixing.

- Added editmesh version for mesh-octree lookups, not used yet.

- Fix: ESC on armature posemode restored the actions, should not happen

- Fix: If in NLA an action was 0 frame long, it caused draw error

- Fix: Click on name in Action Window now activates Bones

- Fix: "Snap to" options in Armature editmode now use X-axis mirror edit.
