Framerate control and first launch arguments

aka the "I should've added this in 2.1" update, I added the ability to change the output framerate, and also a useful launch argument.

Ability to control output resolution

Aside from adding the ability to change the resolution, I also rearranged the layout and other minor under-the-hood changes.

Major quality of life updates.

Added nice Qt styling, and replaced bitrate entry with quality slider, and more things under-the-hood. The program should also be easier to setup now, just follow the instructions in the README.

Progress bar and Auto-download FFmpeg if not found

Added a progress bar with help from @xpscyho based on her fork, and also auto-download FFmpeg if not found, also it should automatically download missing dependencies.

Encoder preset control and FFmpeg PATH detection

This release adds the ability for the user to select from a range of different encoder presets, it will also detect if you have FFmpeg added to your PATH and use that instead of requiring FFmpeg in the same folder as the script.

First release

The first release of TurnH264,
Windows release has dependencies packed in, download the source code and follow the instructions in README.md for all other platforms.
