Page search for specific things on the page (#133)
This will close #65 by allowing you select where on a page you want to search, though I may have gone overboard:  In addition to what's obvious from the screenshot: The default setting is to only search in page names, ~~you always have to have at least one box checked~~, the radio buttons are disabled if you're only searching in the page names, unchecking the "All" box will restore the checkbox state that was present when you checked it, and the input focus is now set to the search box when you open the dropdown. Most of these are in their own commits, if one or more should be removed.
