A list of boolean teamfood flags is now available. Adding a flag to
the list means that the flag is tied to the value of the teamfood
flag.
If the flag is manually set, that manually set value will take
precedence.
If the flag is true by default, the true value will take precedence.
Otherwise, the flag will fallback to the value of the teamfood flag.
