PTFS [TEMP] Bug 7736 Edifact QUOTE, ORDER and INVOICE handling

Handle Electronic Ordering via Edifact Messages

This commits adds files to allow interfacing with book suppliers
using Edifact Messages
Currently this supports transferring files by ftp or sftp
There is also an option to read/write to a local directory
which may be useful for testing or other scenarios

Quote messages are used to create baskets in Koha and will create
the associated bib and item records if required

If the user chooses to generate an edifact order from a basket
an Edifact format message is created for submission

If receiving an Invoice Message a corresponding invoice is created
in Koha and the order is receipted

Suppliers interfaces need to be properly configured to send
the correct budget, item type etc info

For more info on Edifact Formats see
