Include local FontAwesome

Hi,

when testing i saw that the Plugin establishes a connection to use.fontawesome.com. This is in two ways tricky. First: users in the EU need to get a consent for their users. Second: some don’t want to establish a connection, such as me. I use a local version of Font Awesome. Please add an option where Font Awesome can be loaded locally or f.ex. tick an option box where it says, that the website already uses FA. ??
