Handle Dewey and edit before printing

Hello UNM!

I've added in some very basic Dewey handling in quicklabels (we have some libraries that use Dewey and needed it to split lines in a certain way) and also some extremely amateur stuff to allow our staff to edit labels on the output form before printing them to the PDF.  I just used the jquery jeditable plugin to do it, and it works fine as long as you only print one label at a time (which most of our libraries do).  Obviously I could handle the printArray writing much better in the new edited.php file.  This could definitely be improved a lot, but it's working ok for us for now, so I thought I'd share!  Thanks again so much for sharing this with us; we have a lot of libraries that totally love it.
