scripts/strip_geo.php to remove geodata from notices by a given user/profile.

May be slow or run out of memory if run on particularly prolific posters -- not yet optimized for that case.

Note that geodata that has already been sent out to other services (via ostatus, omb, twitter, etc) will not be removed from them.
