Drawonly statechart model

[svenjawendler]

Some users of YSCT only use YSCT for modeling and documentation. They'd like a draw only model:

If no expression on transitions and documentation mode is on: -> do not show warning symbol
Allow placeholders on transitions. ; Draw only mode without validation or predefining variables and events.

Idea:

Provide a drawonly model by selecting it within the new wizard.

Maybe it does not get noticed if it is only in the wizard. A short cut menue item 'new -> draw only model' could enhance usability here.
