Addition of two more Services / Applications.
(1) A PhotoService / Dialog to share slideshows. (2) A Network View service, derived from p3disc for a graphical view of peers. Both of these need a little help to get them fully functional. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@375 b45a01b8-16f6-495d-af2f-9b41ad6348cc
