Updated for B42: Fixes issue where java layer errors are spammed to the log if the player is underground, due to the IsoGrid not handling a -ve Z value (return nil). This indicates the isEnclosed is meaninless underground. When the player goes underground the moodle value is 0.5 (neutral) and will not appear. I added an icon for the right-click menu to indicate the player is underground.

Updated for B42

Fixed issue with MP error generated from incorrectly storing the mod data.

Updated CN translations kindly supplied by Fͥraͣgͫger.
Updated the "toggle moodle" action so the game remembers if the moodle was "off" when you leave and resume the game, so it is not on always by default at the start.

Added option to remove the IsoRegions window option.
Added option to allow the IsoRegions window option for Admin
Added option to allow the IsoRegions window option for Observer+ users.

When the IsoRegions window option is disabled, the Is Enclosed moodle option is still available.

Changed IsoRegions Debug option to not be the top item.

Removed the "Other" menu item as the options in it do not work in non-debug mode.

Uncommented the IsoRegionWindow code so it now includes the "Recalc player surrounding chunks" menu option.

Initial add. Tested in single player and multiplayer.
