Debugger: Beginning of core file support

Browse Source 
* DebuggerInterface: Add method IsPostMortem() to be able to
  descriminate between live and post mortem debugging.
* Add DebuggerInterface implementation CoreFileDebuggerInterface which
  provides information from a core file.
* TeamDebugger: Don't start the debug event thread when debugging post
  mortem.
* Debugger: New command line variant "Debugger --core <file path>",
  which starts a team debugger using the core file.

There are a few issues:
* I didn't see an easy way to integrate with the new
  TargetHostInterface framework and I didn't want to get into Rene's
  way changing stuff. As a side effect core file debug windows are not
  counted and Debugger will quit when only those are left, respectively
  will additionally open a teams window on start-up.
* There aren't any symbols yet. We can't use the debug kit
  functionality, since it isn't bitness/endianess agnostic. So either
  it needs to be adjusted or ported over to Debugger.
