* added OthersList to p3linkmgr. this is important so we can send ACTIONS for removed Peers. * added missing mStatusChanged when adding Friend. * added printPeerLists to PeerMgr and LinkMgr. * tweaked debugging. git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.5-netupgrade@4427 b45a01b8-16f6-495d-af2f-9b41ad6348cc
