Allow multiple commands with ';' separation. By
this also allow empty commands now like {% %}.
Added a little shell based script suite. The tests
aren't complete. But it's a start.
Added some Graphviz generation for MulleScion
object model.
Made a lot of changes, that were needed for the 
move to multiline statements in {% %}. Fixed some
errors en-passant. The object model also changed
a bit.
Made trace output more understandable and usable.
Added Releasenotes, bumped version and the usual
stuff. Fixed dox up to represent the new version
better.
restructured more to my liking
