Emily Toop da599c3a78 Fix broken documentation links. (#775) (#767) r=nalexander 
* Fix broken API doc links

Create symlink for latest to point to v0.7.
Group APIs by top version number rather than individual

* Update swift and android version numbers to match Mentats

* Update documentation

* Update top level .gitignore to ignore docs site & metatdata

* Add README to help with building documentation site

* Address review comments @ncalexan

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
