Adding Basics of GxsChannel Service into libretroshare.
This includes a generic CommentService, which will be used by other Services. + Bugfix, gxs service threads were started before global variables were set. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@6186 b45a01b8-16f6-495d-af2f-9b41ad6348cc
