Bug 36246: Add JS function/include for submitting forms from link data

This patch adds a new js include file form-submit.js which will read data elements from a link
and use those to submit a form

This patch fixes forms on acqui/invoice.pl as an example

To test:
1 - Add some invoices for a vendor
2 - Got to Acquisitions->Invoices
3 - Actions -> Close - confirm it works
4 - Got to 'Closed invoices' - reopen
5 - Go to Details on the invoice
6 - Add an adjustment
7 - Delete the adjustment
8 - Confirm it works
