angular-loading.css not included in bower.json file under "main" key.

I ran into a bug when using the angular-loading component with grunt:wiredep module: Grunt:wiredep combs all local bower_components folders (which are not version controlled) for their dev dependencies for the purpose of minifying them into either a vendor.js and/or a vendor.css file. It does not find or consume/minify angular-loading.css because its not listed in your component's bower.json file under the "main" key. I'm happy to do a pull request "my first one actually on gh"; but since its such a small change, was wondering if you would have an issue adding it yourself to line 17 of your bower.json;

"main": ["./angular-loading.js", "./angular-loading.css"],

and then registering a package update with bower? Excuse me if I'm not going about this right, this is the first time I've had an issue with a specific bower.json file inside a package author's component folder as opposed to my own dev dependency bower.json file. Thank you for this component, it works perfect otherwise, its just the grunt minifying that messed up on my end.
