Major Structural Update and Bootstrap 3.3.0 Update

All templates are now housed in their own GitHub repository. As such,
the templates directory on Start Bootstrap is now all redirects just in
case of old links pointing to those URLs. The downloads directory has
been removed completely, and the downloads are now managed by each
template's respective repository.

In the future I will be adding versioning to each template, but for now
the template download will just download the entire repository.

All templates have been updated to Bootstrap version 3.3.0 and jQuery
version 1.11.1.
