Brecht Van Lommel 19babf988d 2.5: Added operator ui() callback for defining own ui layout 
to show properties.

* One problem is that we currently have 3 different kinds of
  property layouts, single column, two column, and single column
  with text inside button, probably best to reduce this..
* Last operator panel now shows operator name in the header.
* Fix extrude operator to not include transform properties
  anymore, since they are already there now due to macro system.
