• Update the icons list for the last version 5.4.1
• Created a IconTypes object that contains the font families so you can pass through the FontAwesome component properties (Why and How: README)
• Created a parseIconName function so you can parse the font awesome classes to a valid name to use in this component. (Why and How: README)
• Updated the README with the new features

Any chance this can be merged?
