[Feature] Add config optn. to disable jail free tp

Adds the teleport-back-when-freed-from-jail configuration option. When
set to true (default), as with previous versions will teleport the
player which was jailed back to their previous position when freed. When
false, Essentials will not teleport the player anywhere, leaving them
where they are.
