Subject: [PATCH] Fix for Bug 7135: Save button options

This patch adds a jQuery plugin which will cause
an element to remain "fixed" at the top of the
screen if it would otherwise scroll up out of
view.

The license of this plugin is "This plugin is as free as fresh
air. Feel free to use it anywhere.".

Signed-off-by: Liz Rea <wizzyrea@gmail.com>
I tested this on Chrome OSX
saving works
changing framework works
scrolling works, obviously.
tabbing through the records works
z39 button works as expected

updated patch comment about licensing of the plugin
(cherry picked from commit da916a368c98e7f2599cf3a52126d53ee0ecfcd1)
