- 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
