Can't change right margin with margin_right

[aosmith16]

I noticed that all my icons were slightly pushed to the left with the newest version of fontawesome. I attempted to change this via the new margin_right argument and, well, nothing happened, no matter what value I used.

I delved a tiny bit into the code and as far as I can tell that argument is never used in within the fa() function. Instead the right margin is hard-coded at ".2em". Am I missing something?

This is my mistake, sorry that it broke your existing document. I'd like to fix by making margin_right functional, defaulting to the "auto" margin (essentially 0, same as before the update), and adding a margin_left argument (default of "auto"). Once this is fixed, a patch release of the package will sent to CRAN.
