Chemistry, bar and virology smartfridges. Ingestion reagent transfer delay. Piano

Smartfridge variations added to chemistry, bar and virology. One of the virology windows didn't have sides, so I fixed that. Credit for smartfridge variations goes to /tg/.

trans_to_ingest now used for consumption of food, drink and pills instead of trans_to. This adds a ten second delay between ingestion and addition of the reagents to the body.

Piano added to the bar.
