2.5 MetaBalls

 - It is possible to work with MetaBalls in edit mode now
 - Added basic UI to the button window (feel free to change it :-))
 - Header menus should work
 - Undo & redo should work
 - Removed global variable editelems and lastelem (moved it to the MetaBall struct)
 - All tools from old editmball.c was converted to the operators
 - Added lastelem to the RNA
 - Experimental: mb->editelems is only pointer at mb->elems or NULL (depends on Mode). ListBase of MetaElems is not duplicated in edit mode.

Tested with scons at Linux and mac OS X

TODO:
 - Recalc data after Undo or Redo
 - Solve issue with basic MetaBall and Python UI script (only base MetaBall object influence Wiresize and Threshold)
 - Fix orientation of manipulator in "Normal mode"
