Testing has demonstrated that del self.x does not make the memory used to
store x available for garbage collection.
There is clearly an additional reference from another place. In fact
*after* del self.x then the memory can be made available for GC by
assignment (e.g. self.x = None). However I haven't found how to release
this reference and there is nothing in self.__dict__ that can help.
For now we'll use a twp-step process where we set the variable to None
before deleting it.
This has a big impact on memory usage. For Software it is almost 1k
(a.k.a. about 10% impact on free RAM).

Currently the spinner uses exclusive max when wrapping from low to high
and inclusive max when wrapping from high to low. Fix this by adopting
*inclusive* max everywhere. The call sites are similarly confused.
Fix this!

The alarm is off by default so there's no reason to set an alarm that
is disabled. Let's stop doing that.

Currently the widgets react to touch when the alarm is ringing (and they
are invisible. For now we fix this by disabling the alarm on a touch
event. Maybe the app should reject touch events since they could acidentally
dismiss the alarm... but we already disable the alarm if we get a swipe
event so this doesn't make things much worse than they already are!

The long term plan is to retire and remove the 1-bit RLE code from wasp-os
so we don't want new icons using that encoding.
