Bugfix in version 4.460, work I did to make tabs optionally hidden for select job stuffs up tabs in places where tabs cover multiple lines, such as the main setup screen. Some tabs a missing when the cover multiple lines. Now fixed.

Unit line items : permit non dutyable line items to be based on formula. So things like stamp duty costs can be setup as either on road costs or as non duty invoice items. Whichever suits.
