Bug 31432: Make 245$n$p visible by default in frameworks

$n (part_number) and $p (part_name) now have their own
columns in the database, but we are still hiding them
by default. It woudl ease testing and cataloguig if
we changed them to be visible by default in new installations.

To test:
* Check that in your current frameworks when adding a new
  record, 245 n and p are hidden
* Apply the patch and start over: drop your db and run the
  web installer
* Verify that the fields are now visible
