Add Verse master-server functionality

* added two files from verse-master
* server list is available in outliner (new mode "Verse Servers")
* verse sessions are now also in new mode "Verse Sessions" in outliner
* fixed drawing of verse sessions and their nodes
* in user preferences System & OpenGL master-server ip setting (default master.uni-verse.org)
* in File>Verse entry "Get Servers" to get server list or
* RMB on "Available Verse Servers" in outliner to "Refresh" server list

Enjoy :)
