If dest > origin, any blocks past origin.size will drop you at dest[0]
Switched to scheduler instead of our own thread for closing gates and deactivating signs
No longer depend on Permissions, use it as an option. isOp() used as defaults.
Added migration code so old gates/portals are ported to new folder structure
Create default config.yml if it doesn't exist
Fixed removing a gate, it is now completely removed
