Simplification of HG configs: HomeURI and GatekeeperURI now are defined as default under [Startup]. They can then be overwritten in the other sections (but probably shouldn't). I kept the existing code for backwards compatibility, so this should not cause any breaks from people's current configurations. But people should move to have these 2 vars under [Startup] -- see OpenSim.ini.example and Robust.HG.ini.example. And yes, both names now end with "URI" for consistency.
