Fix for issue with sign updates causing huge load on server. This wasn't my code, but will have to take responsibility for not double-checking commit.
Small fix for sign updates some times not working for all of them if you had special signs going before regular ones in the list
Converting some database data back to previous state, this includes job names, world names and all that jazz. We are still using new id system, but for time being and to have backwards compatibility, in case you will want to go back, you will have option. At some point we will have to move entirely to the ID based system which saves a lot of data base space. After all, having id 1 repeating couple thousand times takes less space then repeating entire job or world name for same amount of times.
