Adds the ability to inject chemicals into the atmospherics pipeline thro...

...ugh the following methods:

* Inject into canister and release
* Inject into canister and hook into a loop
* Inject into canister and transfer into an internals tank
* Inject into canister and share between canisters
* Pouring a container (beaker, bottle etc) into an OFF vent

Adds an industrial sized 'injector' to the atmospherics closets to facilitate dispersion of chemicals into the air-stream.

Plasma, Fuel and Thermite in the air will add to the flammability of the air, but not neccesarily ignite it.

99.5% of chemicals can be dispersed, and will react as intended, including viruses, acid, slime toxin, alcohol etc.
* A known "issue", but not exactly an issue, is that explosive reactions (EMP,Potassium etc) will be small.

Here are some previews:

Something after this istype is causing a bug which makes the syringe change what type of output it is doing and bugs the syringe its probably what you are calling in this here to switch its modes you dont need that.
