Animate.css is missing the 'ignore' meta entry in bower.json.

Animate.css is missing the 'ignore' meta entry in bower.json (see: http://bower.io/docs/creating-packages/).  It generates a warning when installing with bower.

Bower Install Warning:
`bower invalid-meta  animate.css is missing "ignore" entry in bower.json`

I've added a simple example of the ignore entry.
