More on HG2.0: added the possibility of controlling the appearance that avies use to visit other grids. Not as good as I wanted, but good enough. Unfortunately we can't switch the appearance from under the avie without getting into a lot of weirdnesses because appearance is viewer-controlled. So instead, when this control is on, I'm disallowing HG-TP unless the user is wearing an allowed HG appearance -- the user gets a warning and needs to switch appearance. WARNING: I'm still not committing the config vars because this is still not ready for ppl to test.
