Basic pattern created, now create a clock!

TODO: create pulse generator, add actionlisteners to the radiobuttons to
decorate the clocks
Clock and pulse created, next: finish decoraters

Next thing to do:
1. Implement the Timezone with EventListeners on the radiobuttons (look
at the 1337-checkbox how to use a Decorator.
2. Fix the 1337-toggles so it changes the colors back again.
