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
