Only rewrite CC to QM1 if Paycards plugin is enabled
Removed deprecated functionality from ReceiptLib:
* reprintReceipt() to longer needed. Because transaction data
  rotates out of localtemptrans *before* printing the receipt
  there's no longer a major distinction. printReceipt() handles
  both originals and reprints
* printCCSigSlip() handled by message mod CCReceiptMessage
* printGCSlip() handled by message mod GCReceiptMessage
* printGCBalSlip() handled by message mod GCBalanceReceiptMessage
Restructured screendisplay view vs DisplayLib draw function so that
switching between the two methods is easier
Updated unit test to account for renamed bitmap file
BUGFIX: IDTech logo needs to be optional. Load errors should not
impact device behavior
Initial driver for Ingenico iSC250 USB. Lots of stuff still missing.
Basic connectivity works on Windows at this point.
