Adds new different reaction types. (#2114)

* Adds new different reaction types.
- Adds touch, injection and ingestion reactions for entities.
- Adds tile reactions.
- Removes GasSprayerComponent in favor of SprayComponent.
- Gives fire extinguishers a safety.
- Gives spray puffs a sprite.
- Improved spray and fire extinguisher in general.
- Fire extinguisher now ACTUALLY puts out fires. Amazing, eh?
- Fire extinguisher sprays three 'clouds' at once.
- Spraying flammable chemicals at fire makes them worse. Whoops!
- Gives spray and fire extinguisher their classic sounds.
- Most chemicals now don't make puddles. Too bad!
- Space lube now makes a very slippery puddle. Honk.
- Spraying water (or using a fire extinguisher) on existing puddles makes them bigger.

* Fix solution tests

* food base now has solution container with noexamine caps
