Incorrect source map for 3.2.0 in bower build

[falsyvalues]

In ng-tags-input bower build v3.2.0, ng-tags-input.css contains /*# sourceMappingURL=ng-tags-input.css.map */ but the file is not minified so link is useless (source map file is missing anyway). I would suggest to remove this sourceMappingURL, it may cause problem with css minifiers that are source maps aware.
