`mcl_vars.hud_type_field` is introduced to determine the right HUD element type field to use. All mods adding HUDs, together with their `mod.conf` files, are changed accordingly to silence the warnings.

Changes made:
* Put in new chatcommand /whereami to allow normal players to turn on / off player location coords without needing special privs.
* Made Debug Coords level 2, Player Location level 1, and Off level 0. (Allows turning the location off.)
* Put in nil value check into get_text, to prevent errors caused by definitions accidentally not returning a value.
* Cached pairs, ipairs, and table because the code is called every 0.63 seconds, and it made sense to do so. (Hopefully, will help
to mitigate the added load on framerate.)
