Subject: *Renamed ParcelManager to LandManager *Made the Parcel class its own
 file and moved the Parcel and LandManager into their own folder in
 Environment *Some renaming might need to be done so the Parcel class doesn't
 have issues with the libsecondlife Parcel class, but Land doesn't seem right.
