implement jqueryui dialog replacements.

For now only alert windows are converted automatically. You can alert custom
HTML code like so: alert('<strong>herp a derp</strong>', true);

Main can use this feature immediately, all plugins that are advertized to be
stable may only use this once 0.7 is released.
