[FEATURE] Growable Oats

[Mordent]

Adds oats as a growable crop, which can be turned into oatmeal in the food processor (i.e. the same way that wheat is turned into flour).

Effect(s)

• Adds the "oat" crop.
  
• Oats can be converted into oatmeal in the food processor.
  

Testing

• I tested on my local build (my changes on top of the goonstation-2016-byond510 branch) and it seems fine.
  
• Can grow oats: yes
  
• Oats can be turned into oatmeal in the food processor: yes
  

Code

• Note, includes .dmi files so as to allow for better pull requests into my develop branch; for the patch just remove everything from diff --git a/icons/obj/hydroponics/hydromisc.dmi b/icons/obj/hydroponics/hydromisc.dmi onwards to get the patch without the icon changes and manually add them to the relevant files (icon state names are "Oat-G0", "Oat-G1", "Oat-G2" and "oat" as relevant)
