- implemented a visualisation for currently handled chunks, availability maps, and transfer info
- 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. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@1939 b45a01b8-16f6-495d-af2f-9b41ad6348cc
