* Cleanup a bunch of things

* some changes dunno

* RequireAnchored

* a

* stuff

* more work

* Lots of progress

* delete pipe visualizer

* a

* b

* pipenet and pipenode cleanup

* Fixes

* Adds GasValve

* Adds GasMiner

* Fix stuff, maybe?

* More fixes

* Ignored components on the client

* Adds thermomachine behavior, change a bunch of stuff

* Remove Anchored

* some work, but it's shitcode

* significantly more ECS

* ECS AtmosDevices

* Cleanup

* fix appearance

* when the pipe direction is sus

* Gas tanks and canisters

* pipe anchoring and stuff

* coding is my passion

* Unsafe pipes take longer to unanchor

* turns out we're no longer using eris canisters

* Gas canister inserted tank appearance, improvements

* Work on a bunch of appearances

* Scrubber appearance

* Reorganize AtmosphereSystem.Piping into a bunch of different systems

* Appearance for vent/scrubber/pump turns off when leaving atmosphere

* ThermoMachine appearance

* Cleanup gas tanks

* Remove passive gate unused imports

* remove old canister UI functionality

* PipeNode environment air, make everything use AssumeAir instead of merging manually

* a

* Reorganize atmos to follow new structure

* ?????

* Canister UI, restructure client

* Restructure shared

* Fix build tho

* listen, at least the canister UI works entirely...

* fix build : )

* gas canister ui slider doesn't jitter

* trinary prototypes

* sprite for miners

* ignore components

* fix YAML

* Fix port system doing useless thing

* Fix build

* fix thinking moment

* fix build again because

* canister direction

* pipenode is a word

* GasTank Air will throw on invalid states

* fix build....

* Unhardcode volume pump thresholds

* Volume pump and filter take time into account

* Rename Join/Leave atmosphere events to AtmosDeviceEnabled/Disabled Event

* Gas tank node volume is set by initial mixtuer

* I love node container
