Revamp the viewer -> banlist packet processing so fix a number of bugs.

Remove the too coarse CanEditParcel method in favor of a CanEditParcelProperties
method that takes a GroupPowers argument to specify what action is to be
taken. Also, make the method to set parcel data much more granular. Permissions
in a deeded setting should now work.
