Add Chromecast YouTube remote control

Hi. I got a Chromecast.

**Verification steps:**

- [ ] ```set RHOST``` to your Chromecast's IP
- [ ] ```show actions``` to see what you can do (not much)
- [ ] ```run``` to see Epic Sax Guy for 10 hours
- [ ] ```set ACTION Stop``` and ```run``` to stop the madness
- [ ] Change ```VID``` to something less obnoxious?
