Minifier - use the absolute path instead of the relative one for the filepath variable

[mathieuhays]

Configuration:

{
    gzip: true,
    minifier: function ( contents, filepath ) {
        if ( filepath.match( /\.min\./g ) ) {
            return contents
        }

        var file_extension = '';

        var minified_filename = filepath.replace( /\.(js|css)$/, function(match, extension ) {
            file_extension = extension;
            return '.min.' + extension;
        } );

        // re-construct a path like: /path/to/assets/js/main.min.js
        var minified_path = path.join( '/path/to/assets/', file_extension, minified_filename );

        if ( fs.existsSync( minified_path ) ) {
            return fs.readFileSync( minified_path );
        }

        return '';
    }
}

Since the filepath only contains the filename I had to hardcode the full path which is not ideal.

To the best of my knowledge I don't think there are other ways to get the full path rather than hardcoding it in this case.

Having access to the full path will prevent us having to hardcode the path on every project.

Optionally we could add the full path as a third argument for backward-compatibility.

Thanks ;-)
