Added pancakes and jam

I have added Pancake and Jam to food recipes. I have added it just
because i need to start coding somewhere and this looked like a nice
opportunity to learn new things. Pancakes are fully tested and works,
with no bugs found.
Thanks to Spheretech for sprites
Fix of potassium and phosphorus quantities in plants

I have halfed quantities of ptassium in potatoes and phosphorus in
pumpkins. Now there is about 1-2 units in normal plant...
Quick fix for pancakes
Minor map changes

Added
- medical data computer in the recovery ward
- O- bloodpacks on the surgery tables
- extra empty bloodpacks in the freezer
- a light in the north western part of arrivals where there is one very
dark hallway leading up to a double door airlock

Changed
-lights around the fitness area where there were a few double lights and
one weirdly placed light

Chemsmoke rewrite

- Chemsmoke now affects a circular area with a variable range depending on the total amount of chemsmoke created (no more 1-of-each-ingredient smoke grenades - sorry).
- The carried reagent volume in the cloud balances itself according to how big the affected area is (larger area, less carried reagent per turf).
- The carried reagent has more volume the closer you are to the center of the cloud.
- The visual smoke effect scales with how big the affected area is.

Other fixes

- Foam reagent inheritance fixed:
The trans_to() proc in Chemistry-Holder.dm was calling handle_reactions() every time it would add and remove reagents with add_reagent() and remove_reagent(). I've added a safety flag to both of these procs (and copy_to()) so that trans_to will not call handle_reactions() until it has added all the reagents to the target container. This allows foam to reliably take on the properties of other leftover reagents.
- Carbons reaction_turf proc now modifies a single dirt overlay layer, instead of just adding more decal objects to the turf.
- Added some checks to the radium and uranium reaction_turf proc so it doesn't stack multiple greenglow decals.
- Performed colon removal surgery on thermites reaction_turf proc, also tweaked it's overlay operation to correctly overlay a chemical puddle effect, instead of a melted wall effect.
- Removed space_cleaners overlays.Cut() code, since it was removing decals from turfs.
No combat punch for non-lethal gygax
Added better checks to leap(), prevented leap spamming (hopefully).
