* Moved the introduction page to the en/latest/index.html home of the documentation and pointed all links there
* Fixed a broken link from+to homepage
* Fixed the javascript of the documentation navigation to allow expand and collapse multiple times.
* Fixed the one typo Andy pointed out
This should make previewing documentation easier.
Also updated the Makefile to now copy the theme dir into the _build/website/ dir. Make connect and Make push work.
