Release time calculation supports countries, hour past midnight anomaly

Any show that airs in a different country than the US (sourced from trakt) and is supported will have its release times assumed to be in the common time zone of this country.

Currently supported are (country name, assumed time zone):
- Australia, Australia/Sydney
- Germany, Europe/Berlin
- Japan, Asia/Tokyo
- United Kingdom, Europe/London
- United States, America/Los_Angeles

If it is detected that the device is set to a US mainland time zone other than America/Los_Angeles (US Pacific), now only shows originating from the US are auto-corrected based on the assumption that shows release at the same local time (e.g. 8pm everywhere, 7 central).
