This is a simple commit to revert a change that is causing grief for users using Font Awesome LESS files

[phiamo]

no sure what this is for ;-) could you explain the use case a bit ? thanks for this contribution

Hi @phiamo

Sure. This commit is simply reverting a deleted file (spinning.css).

This file is still referenced by https://github.com/phiamo/MopaBootstrapBundle/blob/master/Resources/public/less/font-awesome4/font-awesome.less

For LESS users, this is causing the assets to fail when dumping. We then get broken CSS and no styling.

Hi @phiamo

Any chance of having this PR merged?

[phiamo]

@isometriks do you see chances this could break anything ?

[isometriks]

Nope, should be fine. Although I plan on removing any embedded libraries in this repo, so I would suggest against anybody using it this way anyway.
