* Disable breaking floor tiles with the crowbar
It's not fun, it adds nothing to the gameplay and it isn't clear what breaks and what does. I see seriously zero reasons to keep this.
* Actually make it so you can pry off tiles still.
- 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.
Overhauled most doors with new access codes as a result of the code fixes intended to keep departments as pure as possible.

- SmartFridge has been tweaked to look better
- ChemMaster no longer puts the units in bottle names by default
- Trinary filter reads last_flow_rate again
- Operating computer now works based off percentage of health, rather
than real health (note, a tesh at -50 won't die until -100, but it'll
trigger the -100% alarm)
- Clicking on the knob in the canister UI no longer brings up a number
input too small to enter values in the valid range. For right now,
the knob stays, but this may be reconsidered in favor of a
NumberInput if more people would prefer accessibility over
skeuomorphism UI design.
- Pipe dispenser has a bent pipe option again
Adds a Random Ambience Frequency and Ambience Chance Setting under Global, underneath Client FPS. Images here:



Self-explanatory. Random-Ambience-Frequency controls how long before it checks if it can play ambience to you again. Setting it to 0 disables the random re-play of ambience.
Ambience Chance affects the % chance to play ambience to your client. It defaults to 35%, but can be set from 0 to 100 to disable it or always play every time you move into an area or have the Random Ambience check called.

Adds a mech vs mech combat system for the toy mechs earned from arcades and found around the station. You can initiate combat with yourself by hitting a toy mech with another toy mech, or fight another player if you attack a player holding a mech with a mech.
Each mech has its own health stat and special ability that they'll use in combat against each other. How exciting!
Also slightly refactors toy locations and changes toy mechs from being JUST prizes to their own proper toy subtype!
