menutini script -- handle multiple active menus

[Fred T. Hamster]

menutini library

menutini should handle multiple menus:

as long as menus are on different channels, manage them independently.
make sure they are all listening, and they all get to run and fire to right owner.
still have menu timeouts, but make it lovey long time like 14 minutes.
this ensures the menus don't just sit forever, but also gives people a chance to respond.
track the active ones in a list.
