Linkedin command changed

[mdavis-xyz]

I recently upgrade my Tex distribution from 2013 to 2015. Now many of my documents won't compile, because the \faLinkedinSign command has been renamed as \faLinkedinSquare.

Now I need to go through all my documents to rename them, which is a hassle.

Please add \faLinkedinSign again, and just define it as equal to \faLinkedinSquare.

In future, please don't rename the user facing commands.
