Add option to save a debug information report.

- The Tools menu now contains an option to save a debug report for the currently
  debugged team. For now this report contains the following:
  	A list of all loaded images, their base address and their size.
  	A list of all threads active in their team, and their state.
  		* For each thread that is in a debug or exception state,
  		  a stack trace, and a register dump at the top frame will also be emitted.

  Feedback on report format + included details welcome.

  For now, when the option is requested, the report is saved to the desktop
  with an auto-generated name based on the target team and the current
  date/time.
