- Fixes Paper and font tags stacking across rounds, as shown in: 
- 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.
You will need to update config.txt with the following lines:
\## Uncomment this to DISABLE persistence
\#PERSISTENCE_DISABLED
\## Uncomment this to DISABLE maploaded trash/paper/etc from being saved by the persistence system.
\#PERSISTENCE_IGNORE_MAPLOAD
- Add additional can_atmos_pass value ATMOS_PASS_PROC which indicates custom behavior requiring calling the CanZASPass proc.
- The benefit being for the other three values we DON'T need to call CanZASPass at all! We already know the behavior without the overhead of a proc call.
- Obviously any atom with can_atmos_pass = ATMOS_PASS_PROC cannot now call ..() in CanZASPass() since the default behavior would be to (recursively) call CanZASPass()
- This required re-numbering the constants, so I also fixed all code that assumed particular values for the constants.
- Switched all types which overrode CanZASPass with custom logic to be can_atmos_pass = ATMOS_PASS_PROC
- Changed /turf/c_airblock() to skip calling /atom/movable/c_airblock() for the three can_atmos_pass values that don't require calling the proc.
- CanZASPass is supposed to return boolean. Nobody noticed this bug because ATMOS_PASS_YES and ATMOS_PASS_NO happen to be defined as 1 and 0. But thats not a good assumption to make, so lets fix it!
* Large amount of work; Animal taming, shearing. Random animal spawns on sif grass/forest turfs. New PoIs, thermal poncho.
* Combat drone DMI moved to drones folder. Mining Drone subtype added. "Tameable" with ores, will collect and store ores when not in active combat.
* Adjust map_effect interval loop
We have those things you wanted now. Also bumped check time to 5s because 3s seems a lot for the repeated player list iteration. Not horrible but still.
* Also adjust pinpointer because it's not great
* Add a missing span in pinpointer
* Forgot a couple things!
- This was caused by create_spores() being called on seeds which were not registered with the plant_controller (becuase they had never been harvested)
- Instead of registering them, we can just pass the seed datum itself, that is all the chemsmoke needs anyway.
* Mobs can be incorporeal
Prevents step noises, getting shot, etc. Basically living ghosts. Feel free to add more places this should check, but I think this is a majority.
* Fix missing incorporeal floatyness
