set architecture to all
first functional implementation. Now displays the epoch, updated every second. PoC, not finished :)
some boilerplate
Actually works now...
 * use pytz to get timezone info
 * looks for ~/.config/tails/timezone, if exists try to use it, else UTC
 * clock ticks every second
 * boilerplate for preferences dialog
 * renamed classes from tailstime to TailsClock etc
