Update Awesome Font to latest 4.4.0

Hi There, anyone successfully updated the Awesome Font used in ERPNext to the latest 4.4.0? I tried downloading the fonts and replacing the css, font and less folder in assets but does not seem to work…

FA 4+ has fa- prefixes. Maybe we can, but a lot of custom apps will break.

Fix all font-prefixes and send a pull request. We can consider this.
