[Patternfly] Font icons and accessibility

[Matt Carrano]

Just a bit of follow-up from our Wednesday discussion about accessibility.  Liz C identified this link that talks about making font based icon controls accessible by screen readers: http://icomoon.io/#docs/screenreaders

I'm thinking that perhaps we should include this link at the bottom of the Glyphs and Icons page? http://rcue-uxd.itos.redhat.com/visual-styles/icons-glyphs/  Robb, what do you think?
