#61 If lineup clock set to count down from :30, OT lineup wrong

[Dan Streetman]

If the lineup clock is set to count down from :30 (i.e. with a max time of :30), then when it is reset and started for an overtime lineup, which is 1:00 according to wftda rules, it will only count :30 instead of the required 1:00.

Either a separate clock should be used, or (probably better) a Policy should increase the max/start time to 1:00 when overtime is started/entered, if the lineup clock is set to count down from :30.

[Dan Streetman]

Added OvertimeLineupTimePolicy which will modify the lineup clock max to 1:00 if needed when overtime starts, and restore it to its original value after the overtime jam ends.
