[GNC] Sales tax changes and posting an invoice wrong tax amounts

[Adrien Monteleone]

You can't change a rule. This would mess with any other invoices that 
use(d) it. (the tax calcs are done on-the-fly, so if the rate changed, 
those invoices would be wrong if you tried to view them, edit them, etc.)

Therefore, if the rate changes, you have to create a new rule.
