Condiment packs: The Condipacking

Fixed issues with the previous PR.

I could fix the runtimes Aran told me about if anybody actually told me why it'd runtime.

Basically:
- Added condiment packs, which hold 10u each and can be applied to food but not directly ingested
- Made condibottles read from a list to determine their icon_state, desc and name
- Removed a bunch of relative paths
