2.5

- Added new popup menu type, which can be used to pass on a
  running operator too. Needed it for debug menu, allowing to
  set variables outside of operator "first do then tweak" system. :)

  void uiPupBlockOperator()
  
  Don't forget to tell invoke() return that operator now runs modal!

- Test menu: alt+ctrl+d gives the G.rt debug value. 
  
  Values of 0-16 now can be used to shrink areas, stuff like this
  then happens (rt==4):

  Was looking at ways to visually distinguish areas and regions
  better. Yes I know, cute rounded corners, etc. Just testing!
