Added hydroponics crates, graphics and crates themselves into the code.

Added Weed-B-Gone into crates at hydro, also Weed-B-Gone functionality. 
Changed map accordingly. 
Added weedbgone as a reagent and a recipe for it.
Added new spray sound effects and updated/changed those that were used before for fire extinguisher, refueling/refilling, using cleaner and using weed-b-gone.
Removed thumbs.db added by TLE as I saw it unnecessary.
Added buzzing sound to be used later with Fly Amanitas.
Changed some fertilizer graphics in chemical.dmi to be prettier.
