First of all, thank you for adding the fontawesome plugin! Great, I love it! :D

Inserting fontawesome icons works fine. However, there is a problem with adding links to those icons.
Unfortunately, adding a link is not possible in the "editor view" of JCE.
You can set a link in the "code view" and it will remain when you save - but only if the article is saved from the "code view".
If you switch to the editor view and click save, JCE removes the link from the icon.

It looks like the code is being cleaned up and <a> tags are not allowed on <span> tags.
Is there a setting somewhere that prevents this?
