missing
finished a sketch of commit 59523000fc
Move functionality to wait_for_resume() in utils.c
Indent debug messages so you can differentiate them more easily

Bottle::pour should not print delay_until errors
fix protocol: "POURING int int" not "POURING str int"

first int is number from 0-n, not the bottle name
remove Bottle.name

not needed, we will never be able to keep this up to date...
