Added commands for region flag management

Added a register for valid region flags at which
each new flag needs to be registered at.

Fixed some more minor and major derps
Fixed some more derps ofc.

Removed the registration of flags into config for boostrapping purposes.
Added list/edit of global flag properties.

Creeper explosions are derping, there's a flaw in the logic
that removes affected blocks from the list. It always comes out empty.
Needs fixing.
