VIP and VIP+ players can now change their own spawners by right-clicking them.
Everyone can only change/edit their own spawners.
Everyone can only destroy their own spawners.
Donors can pick up spawners without silk touch, but the sapwner will revert to a pig spawner (It's default state). Silk touch is required for the spawner to keep its mobtype. All players can then move a spawner with its mobtype, as long as they have silk touch.
