Fix removing the default background image for themes that hard-code the default in css. Honor the default background image for themes that do not provide a fallback in css.

* <style> will appear if there is a default image registered. This is the same as 3.3.
* If only a default color is registered, it still assumes it is in the stylesheet, and no <style> will appear. This is a change from 3.3.
* <style> will continue to appear as before if there is a custom background color or image. This is the same as 3.3.
* This then allows for a default background image with background-image: none, overriding style.css. This is new.

Remove user/site suggestions (autocompletion) from search inputs, as the UX isn't proper.
 * Removes all instances of site-search, so away it goes. Sidesteps a number of bugs with site-search.
 * Renames user-search to user-suggest, which means it better describes the current behavior (autocompletion) while allowing for future behavior (instant search).
 * Ties user suggestions to a single .wp-suggest-user class.
