2.5

- depricated area "headbutofs" and "headbutlen", which is now fully
  replaced with view2d handling. 
- needed to add header default V2D_ALIGN_NO_NEG_Y, V2D_LOCKOFS_Y seems
  to not do anything atm :) 

- new: running blender in debug (blender -d) will print the current
  handler and operator in use (not mousemove)
