Render the HTML for autocomplete results server-side instead of in
Javascript. This is cleaner than building HTML in Javascript, but it may
hurt caching because the HTTP responses are larger.
Fixes#4698: user autocomplete contains links to /posts
Also fixes a bug where tag counts in the autocomplete menu were different
from tag counts displayed elsewhere because of differences in rounding.
Components are used to encapsulate common UI widgets used throughout the site. This includes things like comments, tag
lists, post thumbnails, paginators, and other things used repeatedly throughout the site. Components encapsulate a
widget's HTML, CSS, and Javascript together so that all the code for a component is in a single place.
