JSCS reporter compatibility

[VWoeltjen]

I'm having some compatibility issues when trying to use the jscs-html-reporter

This works fine:

$ jscs src/ --reporter jscs-html-reporter
>> jscs report written to /.../jscs-html-report.html
Too many errors... Increase `maxErrors` configuration option value to see more.

But this does not:

gulp.task('checkstyle', function () {
    return gulp.src(paths.scripts)
        .pipe(jscs())
        .pipe(jscs.reporter('jscs-html-reporter'));
});

When I run this task, I hit an error with that reporter:

$ gulp checkstyle
[13:03:42] Using gulpfile ~/.../gulpfile.js
[13:03:42] Starting 'checkstyle'...
/.../jscs-html-reporter.js:14
    var config = this.options || this,
                     ^

TypeError: Cannot read property 'options' of undefined
  at module.exports (/.../node_modules/jscs-html-reporter/jscs-html-reporter.js:14:22)
  at DestroyableTransform._transform (/.../node_modules/gulp-jscs/reporters/index.js:21:4)

(Full stack trace omitted for brevity.)

I'm guessing there is some difference between the way jscs normally invokes a reporter, and the way it's getting invoked from gulp-jscs. It would be useful to have sufficient compatibility with vanilla jscs to use this reporter.

I have found the gulp-jscs-with-reporter and gulp-jscs-html-reporter projects, which provide a workaround to this, but I would prefer not to switch to a fork of gulp-jscs for this one feature.

Supporting a jshint-like syntax for reporter options would also be useful, e.g.:

gulp.task('checkstyle', function () {
    return gulp.src(paths.scripts)
        .pipe(jscs())
        .pipe(jscs.reporter('jscs-html-reporter', {
            reporterOutput: __dirname + "/jscs-report.html"
        }));
});

@VWoeltjen just an FYI - I have added support for gulp-jscs to jscs-html-reporter.
