Add Bootstrap 2.2.2 CSS (Without Responsive, Without icons)

The current naming structure isn't ideal, as bootstrap.no-icons.min.css also contains the responsive CSS, so I added a version named bootstrap-combined.no-icons.min.css, which is the same, but with a clearer name. So, the only real addition is bootstrap-only.no-icons.min.css, without responsive CSS and without icon CSS. Ideally in the next version, the name would be changed to simply bootstrap.no-icons.min.css to keep with the original naming structure.
