Prevent Garlic Oil from being poison

[Typhin]

Description of changes

Tags garlic oil as injectable_nutrition. Because this causes adjust_mob_nutrition() to get called twice, nutriment/hydration factors are cut in half to compensate.

Why and what will this PR improve

Garlic Oil now can be used as an antibiotic without dealing 1.2 TOX damage per unit ingested (due to a food substance being present in the bloodstream).

Hmmm I don't much like having it process twice, it means immunity and such will be adjusted twice. Not sure of a better fix short of duplicating the logic into affect_ingest on garlic juice specifically, which is gross too.

The only other thing I can think of to do is have affect_ingest() basically skip all processing if it has both injectable_nutrition and affect_blood_on_ingest so it only processes once. (And since affect_blood_on_ingest is a ratio value rather than simple true/false, it could do something like digest_amount = (1 - affect_blood_on_ingest) and then use that to multiply the effects of digestion. Basically it only processes the total amount but in two passes, but an ingest portion and an inject portion.)

The "duplicating logic into affect_ingest()" unpleasantness is why I went with the affect_blood_on_ingest route, only to run into the "food in bloodstream deals TOX damage" problem.

Going to approve this for now but I might revisit it with another solution in the future.
