First attempt at getting the signs of cells to display information #31

The variables possible are:
* %player% - the player's last known name
* %uuid% - the player's uuid, or what can fit on a sign
* %reason% - the reason the player was jailed
* %jailer% - the person/thing who jailed this player
* %afktime% - the amount of time the player has been afk
* %timeinminutes% - the amount of remaining time the player has in
minutes

If the player is jailed forever, then it pulls from the language file
`jailedforeversign` property.
