fix handling of query & config options
fix handling of query & config options

Before this commit webfonts-loader didn't handle options from webpack loader query, and didn't handle some options from font file config, including the "dest" option. This caused webfonts-loader to insert publicPath as a prefix to every font url() in CSS, which breaks css-loader because it isn't suited for resolving absolute CSS url()'s.
