jQuery, Header, and Footer 4/4

Merge fourth and last! (After jQuery, Header, and Footer 3/4 https://github.com/otwcode/otwarchive/pull/1104)

Part of the jQuery update: removes the qTip tooltip JavaScript form the list of items being loaded on every page and move it onto the only page it is needed, the tag set nomination show page. Moves the qTip-specific JavaScript from application.js onto the tag set nomination show page and adds jQuery migrate to that page to keep qTip working until an update comes out. Updates the styles for qTip to keep them working.

It only has a separate branch/pull request because I was originally going to do something different.
