Comment 2 for bug 1748277

I've pushed up a branch here that should resolve this: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/khuckins/lp1748277-patron-reg-long-field-doc

It rescaffolds the patron editor, letting Bootstrap handle a bit more of the layout, and brings the z-index of the patron alert's pane up to 3, in order to avoid issues with the datepicker and any other input fields under form control.
