Add timezone name aliases about apple.py

This can be achieved with the pytz module. On a related note, storing location would be much preferable to just storing offsets as I do now, because that would deal with DST better than it does now (meaning: at all).

DST could be potentially separated into its own setting, as some regions don't participate while literally everyone else surrounding them does. Other than adding logic for that, it'd make sense to at least have some sort of override in that scenario. I do +1 the idea of adding DST in general though.

Much the same as #111 if we store things in the same way they're given (etc, mst, etc). Closing that to get attention here.
