1.4.6 extras for Invoices

[Benjamin L. <ben...@co...>]

To Dieter, and anyone interested,

Attached are:

IR.pm IS.pm bin/mozilla/ir.pl bin/mozilla/is.pl

These files should be able to used as drop-in replacements for the
similarly named files in SL 1.4.6. Your mileage may vary.

The small changes that I have made are:

* CGI.pm hook workarounds, so-to-speak, for developers. If the user
  doesn't have CGI.pm, everything still works (knock on wood)
  ;-P. These are minimal at the moment.

* Invoice work flow allows 'Update Form' to be _accidently_ used in
  the place of 'Add Item'. Basically it calls the 'Add Item' code to
  check to see if the user meant to press 'Add Item' if there is some
  input in the bottom-most line.

* Invoice has autocalculated Due Date on 'Update Form'; based upon
  customer / vendor's credit terms. So the user can post an Invoice
  tomorrow and have the Due Date calculated for them? Ha. Probably
  needs a manual override.

* Invoice 'Update Form' checks for valid item Numbers in the rows; and
  removes the line if invalid. This would occur if the user accidently
  was to change an item Number for any row bar the bottom-most line.

And I've include Form.pm because it's got some CSS stuff in it. That
may (or may not) make your browser use smaller and different fonts.

Have fun,
Ben.
