per-user timezone, dialog_generator.php had changed from 1.2.6.2, but i don't see it in the dev branch anymore

meant to make this a different branch, but i messed it up.

didn't add in timezone to the user preferences page yet, i was testing it with my settings hooks (coming next pull).

it was really quite easy to add the per-user timezones with the way you had the code structured. :)
