- implemented a visualisation for currently handled chunks, availability maps, and transfer info

Browse source 
- implemented transfer protocol for chunk availability maps between peers (not enabled yet though)
- suppressed rsiface directory from retroshare-gui
- moved notifyqt.{h,cpp} to gui/

next moves: 
	- send availability maps to clients; 
	- connect turtle search to unfinished files;
	- test multisource download with unfinished files.
