Fixes #4221.
Added filling_color var to food items for use in sandwiches.
Added sandwich topping and filler mask.
Ticked sandwich file that I accidentally included in prior commit. Sandwiches are now a thing that can be made from bread slices.
Icon fixes, shards hidden in food will now lacerate random body parts because damage code is weird. Stop eating chocolate cake sandwich with your left food.
Colour fix for bread slices.
Runtime fix for people that jump back in their body before hitting respawn or just stay in their body for 30 minutes.

Who does that?  People that cause runtimes, that's who!
