- Fixes Paper and font tags stacking across rounds, as shown in: 
- Fixes Graffiti being persistent for over 50 rounds (10+ days)
- Sets Trash to be persistent for 4 rounds instead of 5
- Fixes Persistence being always-on because of if("persistence_enabled") config.persistence_enabled = 1. As explained:
> it's on by default, which means config.txt will be read and if it's not there it stays at 1. If it is there,it gets set to 1. There is no way to disable it
- Adds config options to enable/disable **Persistence for Maploaded objects**, as well as a verb to toggle such.
- Adds Persistence to config.
Currently IGNORE_MAPLOAD for Persistance is **Disabled.**
Maploaded objects/dirt/etc will be saved by persistence, preserving current behavior.
- Instead of independently spawn'd while/sleep loops, it stores its state and lets the MC fire it.
- Convert relative path indentation procs to absolute path as per modern style standards.
- Break apart the inner loops into separate procs so you can see what is actually going on.
- It now shows up in MC tab, along with stats about what phase it is in.
- Remove duplicate pick_random_edge_turf resulting from our simultaneous addition of it (in overmaps PR)
- Disable SSgame_master and SSevent_ticker subystems, we are still using the original events subsystem.
- Disable the game_master implementations as we are not using them.
- Comment out references to SSgame_master since we are not using it (yet?)
- There is a new option in the player panel labeled "Send back to
Lobby", which will send a given player back to the lobby.
- The player panel also has a shortcut to the "Spawn Character" verb.
- Finally, there's a new config option that disables the warning
message about multikeying if two mobs with the same CID are found;
this option should NOT be enabled if multikeying is prohibited by the
server rules. It is simply a developer tool, as multikeying is
sometimes necessary to test new features that require two clients
interacting.
