/**
 * This activity shows the settings menu.
 * 
 * Rewrite to support actionbar (backwards compatible to API7).
 * 
 * Could be even better by supporting a modern layout on tablets in landscreen
 * mode with PreferenceFragment I guess, but seems to be a bit more complicated
 * and provides almost no use since preferences are not accessed very often.
 * 
 * For example how to do it right:
