QConn / QConnDoor clients and base functionalities for future Target File System Navigator UI

Finally, after months of refactorings and simplifications of the plugin I reached the state, where I can design and add some new functionalities. Let me then proudly present my own extensions:
 * implementation of the QConnDoor-service client - it's no more needed to have blackberry-connect.bat running in the background to let GDB communicate with the device; all communication establishing is now handled by the plugin itself; it has also this advantage, that doesn't leave any orphan Java processes in case of Visual Studio crash or just shutdown during plugin development;
 * own QConnDoor client allows to have Visual Studio running in parallel with Momentics or with multiple Visual Studios, all accessing the same device; also establishing connection with device is much faster now
 * implemented some basic QConn-service client; it can now:
  - list processes
  - terminate specified one
  - navigate over file system
  - download file or folder into zip-file, make direct copy onto local file system or put into memory buffers (for preview functionality) - they are all processed in bulk mode, with full progress monitoring and totally asynchronous to navigation over file system
  - upload file or folder from local file system  
 * QConn client let replace former GDB processes-listing functionality, what finally added full support for *PlayBook* development!; unfortunately I could only test it with latest tablet OS version 
 * added 2 additional debug-output-windows - first for live preview of the GDB communication, second for QConn communication

I would really like someone from BB to review and test this code; I wrote it completely without any documentation and just by guessing the protocol or by observing how Momentics is doing it; also any tips how to capture runtime logs from the process running on target device could be vital

Next I will add UI to express better functionalities provided by QConn client; I want to add tool-windows for processes management and accessing file system on target device.  

Any comments welcome.

Thanks.
