Any band can be added to the schedule for a day phase, when a
coordinated band slot is not available a random band will be chosen
from all the bands enabled for the current phase (Day, Night, etc.).
Fine tuned the size of the hopping schedule table widget.
Coloured the coordinated band columns in the schedule table widget.
Due to the full range of bands now being supported, the settings key
for the band hopping schedule has been changed forcing current testers
to redefine their schedultes.
