Title: Make html_document_base more universal

Move the bootstrap and jquery dependencies and theme options to
html_document rather than html_document_base. This decouples the jquery
and bootstrap versions from html_document_base, so it can be used with
bootstrap 3 for instance.

Existing functionality should be preserved, although I am not terribly familiar with all of the dependencies in the package.
