Chemistry

**Reagent Colors:**
Changes reagent colors according to [this forum post](http://baystation12.net/forums/viewtopic.php?f=5&t=11558#p249303).


**Additional changes:**
 * Edits all preexisting bottles in the code to use the new bottle sprites and spawn with lid.
 * Solid reagents in beakers will have a mask to actually look like pulver.
 * Pure gaseous or solid reagents cannot be put into syringes or droppers, however can be mixed with any liquid to be dissolved.
 * Edits some visible messages that always expected the reagents to be liquid.
 * Turfs and blood splatters will now hold up to ten units of reagents which can be picked back up using a dropper or syringe.
 * Attacking yourself or another person with a drink on harm-intent will cause it to be swallowed as a whole. The time it takes to be swallowed is proportional to the reagents it contains, or at minimum three seconds if it is forcefed.

**Possible Change in Future:**
Making pure gas in open containers slowly escape to their surrounding environment? Thus, adding every gaseous reagent to our atmosphere system and giving them their unique features? (these would be Hydrogen, Chlorine and Fluorine)
Deliberate?
