Add pause/resume/stop functionality

[MrS0m30n3]

I think it would be really useful if you could add pause/resume/stop download functionality on youtube-dl. I tried to implement it you can take a look here: https://github.com/MrS0m30n3/youtube-dl/commit/3d6a61be64e9bde330fc5efa082fbbbe8081013f
I also added an easy to use YoutubeDLExtendedObject with auto command line parsing.

Just a hint: youtube-dl automatically resumes download if you use the same parameters and the same file name.

@MrS0m30n3 How to send the pause/resume/stop commands?

[AGSPhoenix]

If you want to pause or stop the download, just press Ctrl-C, and youtube-dl will exit. Run the same command again, and youtube-dl will resume the download where it stopped.

@MrS0m30n3, that's quite a sizable patch, but I've mentioned it in the IRC channel, and someone should take a look at it eventually.

@MrS0m30n3 If you want code to be integrated into mainline youtube-dl, please submit a pull request. That allows us to discuss and review it together.

@MrS0m30n3 Looking at the differences, they are huge. Make sure to split up large changes into multiple small (obvious) ones. Additionally, I would strongly discourage splitting youtube-dl into normal and extended - what would you do if someone else has another improvement? Call it advanced?

I'm closing this issue now, you can simply kill youtube-dl and then re-invoke it.
