form_list does not use Base_edit

XXX TODO Formulator checkbox must be modified to not render an input when the field is in read only
Otherwise, in listbox, it creates an input inside a `a` element, which is not valid html

This reverts commit 689e242c.

Commit a01da084 failed to fix the
handling of parameters in the dealShebang function and the bug is now
triggered since slapos@f834a06f:

$ PATH=...  SLAPOS_TEST_LOG_DIRECTORY=... SLAPOS_TEST_SHARED_PART_LIST=... /bin/sh '-e
' /srv/slapgrid/slappart0/t/.../i/0/bin/runTestSuite ...

The script now has a drop-in replacement in `erp5_trade` which works as-is even
in the case of advanced trade (calls `Movement_isQuantityEnabled`). Henceforth,
the custom script in `erp5_advanced_trade` is not needed anymore.

The two scripts were a bit too independant from one another, sometimes causing
weird behaviours. Editing a quantity now depends on the quantity being enabled,
which happens when the line is not expected to have cells or sublines.

Also enforces expected behaviour for items: if a product or service has
*required* items, its quantity cannot be edited, since quantity of the items
should set the quantity of the line or cell.
