[Oberon] WinAos debugger

[Felix Friedrich]

Many people asked me how to use the external AosDebugger in WinAos to 
detect what is going on in cases when the system gets stuck or fully 
loaded. Here it is:
1.) Start AosDebug.exe
2.) Open Menu "Debug"
3.) Click "Start"
4.) Click "Open"
5.) Browse to find and select "Aos.exe"
6.) Click Ok
Steps 4.)-5.) may be omitted next time opening the Debugger.

 From then on, traps are also reported in the AosDebugger GUI and even 
the stack state of all currently running processes can be viewed in the 
debugger (using menu Action->ShowAllStacks).
