Make MainClock more self-contained and generic by moving logic from the Config system and to the class itself, while making the class less aware of how it is used in the config system. It is slightly dirty to store the initial AudioClock widget name in MainClock, but less dirty than having to pass the whole name correctly every time the delta mode changes. Also avoid confusing use of 'mode', which in AudioClock is used for the units/formatting of the clock.
