Icon synonyms in search

[AlgyTaylor]

I don't know if this is realistically possible, but perhaps. I've been trying to find a tick / check and 'cross' icon within FontAwesome, but have been struggling a little in the docs. It'd be amazing if I could type something like "yes" or "positive" in to the icon search, and get a list of icons that could be taken to mean those things (check, check in a circle, thumbs up, ..). That'd be incredibly useful.

I know it's more a FontAwesome thing than a SemanticUI thing, but it'd just be incredibly helpful.

Keep up the good work by the way, I'm a long time fan of your documentation. It's so easy to find what I want generally ...

This isn't to much to change, this is already implemented on the FUI docs. @exoego created a PR for this fomantic/Fomantic-UI-Docs#67
