* Fixed a bug with field data storage that was preventing the admin console from working properly

* Extenders now report their position and the field is extended to include them, the same as markers
* Generators take longer to break with the matter manipulator
* Fields no longer erroneously report an overlap when they're edge-to-edge with another field
* "Hiding" is now replaced with appearance options: "standard", "blocks" or "invisible"
* Appearance setting is remembered across loads and can no longer be changed while the field is active
* The generator will attempt to force load the entire field region before applying or removing the field - if this fails, you get an error "Failed to load region" and can wait a few seconds and try again
* Generators now show an "admin override" checkbox if you have /admin enabled - if this is checked when you activate the field, it will ignore overlap errors and overwrite the entire area (useful for cleaning up orphaned fields)
* There's a new "Field Admin Console" object, which can be used to break all generators on the current world and clear their fields. It can't be crafted, so spawn it with "/spawnitem pilch_shieldadminconsole" while in /admin mode (it also only accepts input from admin players)

Initial version.
