Minor bug fixes

• Regression fix with surcharging. Last version made some heavy changes on surcharging.  For payment methods with a minspend triggered surcharge the minspend trigger was broken. The txns under minspend, payment screen would pop and correctly would not request surcharge but when you press F10 to continue the system incorrectly thought surcharge was needed, not yet inputted and would pop surcharge screen. Now fixed
• SMS Sender ID setting, first real attempt to use this today didn't work. The default declaration message was not exactly correct message needed by our provider. It was fine for our internal testing since we were registering sender IDs relevant for c9, but no good for dealers where declaration needed to be worded slightly differently. Hopefully now fixed.
