This patch replaces all homegrown timezone stuff with standard PHP date/time code. The main change is the introduction of core_date class that returns normalised user and server timezones. From now on nobody should be using $CFG->timezone or $user->timezone directly! Other new features and fixes: * admins are prompted for timezone during install * editing of other users is finally fixed * timezones are displayed in user profile * new $this->setTimezone() in phpunit * time locale is now automatically reset in phpunit * timezone is now automatically reset in phpunit * phpunit has Australia/Perth as default timezone
