Temporary commit to back up data.
Fixed supply shuttle bug wherein the area types were actually tags.
Fixed some bugs regarding space lighting.
Set lighting overlay's name to empty string.
Smartfridge variations added to chemistry, bar and virology. One of the virology windows didn't have sides, so I fixed that.
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.
Changelog updated.
Merge branch 'dev' of https://github.com/Baystation12/Baystation12 into dev
