Task hangs on re-run

[sjwilliams]

If an output target already exist, ffmpeg hangs, causing grunt task to also hang. For now, I've been using a grunt-contrib-clean task to remove old files, but this should be incorporated into grunt-responsive-videos.

have you tried passing the -y option into ffmpeg?

@seanhellwig, I didn't even know that flag existed. I went to explore the bug and it turns out I already had logic to delete existing files, but had failed to do so for poster images. That's what was hanging. I'm now checking that path with the same logic. Fix here: 0c5f615 Thanks for the heads up about -y.
