This patch adds a new system preference: PatronQuickAddFields
When either this pref or BorrowerMandatoryField is populated this will add a new dropdown to the bew patron toolbar. When a category is chosen from this dropdown the fields in PatronQuickAddFields and BorrowerMandatoryField will be displayed. There will be a button allowing a user to switch from the quickadd to the full form and fields will be copied between the forms when toggling.
The Quick add will only be displayed on add of a new patron, future edits should display the full form.
