Clear settings and page blocks on roster

[rozzingit]

Is your feature request related to a problem? Please describe. I believe that, at present, when someone picks up a previously-played roster, it retains the same @settings and page/block and /allow lists. This can be odd for a new player, particularly if the character was left ic_only or with certain people on page/block and the new player doesn't even realize.

Describe the solution you'd like When someone rosters (or picks up a roster), along with the other items that get cleared, everything in @settings should be restored to default, and the page/block and page/allow lists should be cleared. I think that @options mostly is self-updating on connection, but might want to clear any of those that have been manually saved.
