*** Debugger Refactoring - Step 1 of 2 ***

We want to get rid of MorphicDebugger and MVCDebugger variations while keeping Debugger as simple as possible. So, we move GUI-framework-specific (scheduling) code to MorphicProject and MVCProject.

In this first step, we set up the new hooks for Morphic and MVC:

#debugProcess:inWindow:
   #prepareProcessForDebugger:
   #openDebuggerWindow:
   #suspendProcessSafely:
#resumeProcessSafely:

Thanks to Christoph (ct) for the idea and constant reminding that I should finally review and commit this. :-) Note that I feel responsible for any bad naming as I decided to rewrite some parts of the interface between Debugger and Project. ;-)

Note that SavedExtent is not available anymore in Debugger but will be back soon. Sorry for any inconvenience.
