Fixed bugs with Whites Power Sports integration. Was working on our test systems but nowhere else. Should be fixed now

Tweaks to PC-EFTPOS.  By default if PCEFTPOS sends a query back to c9 asking "Customer Copy?", c9 by default will now automatically answer Yes.  Intent here is that we do not want to unnecessarily pause and risking failing txn finalisation with non essential post txn processes such as receipt printing.  At this point the txn has gone through but PC-EFTPOS is withholding telling c9 this.  Had an instance where operator walked away from the terminal and the txn in c9 cancelled due to timeout.  This change will only impact a couple of setups/ banks where this question is sent back via the terminal.
