Customize rating icons

Hello, first of all big thanks for this great work and especially recent updates that solved many of previsou issues!

Would it be possible to customize also icon in Rating module? Besides the star and hearth (i.e. positive) icons also many others would be useful (especially smilies, thumbs, warning etc.). 
I have tried to manually add relevant icon glyphs in my project but it is really time consuming. 

Actually there is a lot of settings/behaviours possibilities for Rating, to add specification of icon within Semantic UI build in Icon Set would be very welcomed.

Thank you for your attention to this suggestion.
