Bug 7977: QOTD uploader to enable uploading csv files containing quotes

This series will add a DataTable's based upload/editor with which
to upload csv files containing quotes to be used by the QOTD
feature.

The file should be formatted thusly:

"source","text-of-quote"
"source","text-of-quote"
...

Note: This work serves as a good example of potential improvements
in all other "editor" and file upload areas of Koha.

This patch is a squash of the following work:

--Adding code to parse CSV file contents and push it into a DataTable
--Adding in jEditable to enable table editing
--Adding ajax to post data back to the server to be saved
--Fixing edit and adding delete functionality
--Adding some missing css as well as server feedback on save
--Fixing a bug which limited the number of quotes which could be uploaded
--Also fixing a minor bug with fnCSVToArray and doing some style cleanup.
--Adding sanity checks to verify file type and size
--Implements YUI button widget/toolbar
--Improved handling of hiding uploader UI
--Adds row selectability
--Adds multi-delete capability
--Adds YUI button/toolbar widget
--Fixing capitalization in quote uploader
--Implements improvments suggested by jcamins and oleonard
