Only Supports FontAwesome 4.7

[jasonfb]

This gem does not support FontAwesome versions past 4.7. That means that if you use it, you will want to search for fonts within the 4.7 font-awesome catalog only which can be found here. If you really want to use this Gem with font-awesome past 4.7, there is some successful discussion of monkeypatching on #194, however, this is also recommended against on the same issue.

Some alternatives to this gem for Font Awesome versions 5 and 6 include:

• font-awesome-sass
https://github.com/FortAwesome/font-awesome-sass

• font_awesome5_rails
https://github.com/tomkra/font_awesome5_rails

• font_awesome_pro5_rails
https://github.com/krtschmr/font_awesome_pro5_rails

IMPORTANT: If you use Google to search for "font awesome" you will find the current FontAwesome 6 icons. Some of these icons may have been in 4.7, but many will not work because you need FontAwesome 5 or 6 for the current icons.

Info about the supported icons and a link to them would be good for the readme.
