gulp-tslint: Does not seem to do anything

Hi,

I just got a fresh copy of gulp-tslint from npm. Unfortunately, when I pipe my .ts files into it, nothing seems to happen - even running your sample code does nothing:

var gulp = require('gulp');
var tslint = require('gulp-tslint');

gulp.task('tslint', function(){
      gulp.src('source.ts')
        .pipe(tslint())
        .pipe(tslint.report('verbose'));
});

I would at least expect some error since source.ts does not exist on my system.
