I remember from attempts to interface SQL ledger that calling the new invoice 
script the invoice number was automatically generated inside SQL ledger. This 
did break when for some reason the next in sequence was already taken. It did 
not choose next in sequence + 1 and try that but rather refuse to set a number 
automatically.  

Conflicts are possible and letting LSMB generate an invoice number would be 
better as long as it hands back that number for reference to GNUmed.
