Add search to HB icons page

Icons that can be embedded into HB themes from here (http://documentation.hb-themes.com/icons/) are nice, but there is no search / filter feature.

I would be nice to see ability to search for say “mail” and only see the envelope icons. Obviously, the icons would need associated tags to search for, but that’s fairly easy to implement.

Let me know if you can implement this in the near future, it should benefit a lot of customers, in my opinion.
