4.0-r1

First version of 4.0.

This was supposed to be 3.0-r5, but I've already bragged that the previous version was the final version of 3.0.

• If you don't use the recording feature, FFmpeg will now no longer be required.

• Reformatted and retweaked the README.md, You should re-read it to avoid losing the information.

• Fixing potential issues and code efficiency improvements.

• Full Changelog: 3.0-r4...4.0-r1

For feature development, I'm currently looking for some specific StripChat streamer that:

1. Previously changed their username, and knowns the previous username.
2. Are actively streaming.
3. Regular streaming schedule.

If you got some name, email me.
