flow_init: <start> | <interval> | <colour list>

Initializes the show flow system; this can also be used with reset_chat to reset for a new show without a full reset of Wintermute.

• start is the time of the first group in the show flow, in 24-hour HH:MM format
• interval is the interval between groups in minutes
• colour list is a comma-separated list of colours that will be cycled through to identify groups. All colours in the .net KnownColor enumeration can be used:

Start is only relevant if not using the flow queue system - Interval is still relevant in this case as it's used to calculate the clock timer.
