Updated the NSString category with the latest icon. A refactor was needed to update easyly the icon values and a better way to convert to FA string from an Enum value in HEX.

The Enum has the same name convention than the CSS file on FA website, but keeps the older names for backward compatibility.

Fixed the Random icon generator in Demo App accordingly to the new enum based icons.
