[Koha-patches] [PATCH] Bug 6269 - can't undefine a printer profile

[Chris Nighswonger]

This patch adds a 'No Profile/N/A' selection to the printer profile
drop-down menu along with code to handle the selection of it. This
selection is the default selection for new templates.

Documentation should be updated to reflect this change.
