Committing docs and changing urls to not be double namespaced essentially

* Removed `tour` from the name attribute on urls as it was redundant.
the appropriate changes have been made to all instances of url and
reverse that use these urls.

* Documented the jquery mobile code so that it is clear as to why
things are the way they are.

* Removed unnecessary blocks in the head of site_base.html as they are
only used if pages are accessed directly and not through ajax via jQm
