[Koha-patches] [PATCH] Fix for Bug 7135: Save button options

[Owen Leonard]

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.

I submit this patch for TESTING ONLY because
the plugin was not posted with explicit licensing.
I'm waiting to hear back from the author.
