Doesn't respect 24 hour setting

[humdinger]

This is hrev32189.

The Time preferences should respect the 12/24 hour setting. The Deskbar setting could be used for that, but ultimately that's of course a LocaleKit thing.

The locale kit will eventually handle all the date&time formatting, you just send it the unix time and you get a BString back. It seems a good idea to wait for that instead of adding more hacks I'll need to remove when integrating the locale kit in the system :)

Then take this ticket as a little reminder when the time has come. :)
