Include only part of font-awesome
<p>I need font-awesome to have spinner icons.</p>

<p>I could include the whole font-awesome library. But wouldn't that be an overkill for just one icon? Is there a way to include just one icon or component? The problem seems to be, that the library is not modularised to different files. For example, if using scss, all icons are in _icons.scss file, rather than each icon in their own file. If you use pure css, then everything is in one file.</p>
