Bugfix with recent changes to SMS/email notification. If system sends two notifications in quick succession it could in some circumstances break the c9 terminal with database errors, requiring c9 on the terminal to be exited to sort out.  Now fixed.

Point of sale ordering involving parts with $0 retail price.  System would not allow you to add deposit. Now fixed. Typically $0 is put in because actual retail price is not yet known.  A deposit is still to be taken as a deposit of the approximate figure.

Spares - > Deposits. Only show invoices where deposit makes sense. i.e. where there is a deposit already or if the invoice involves ordered or set-aside parts.
