Use one archive

There are bundled face tracker and non-bundled face tracker builds for convenience and file size considerations

Provide builds on Windows, Linux and Mac

This should be handled once #15 (ci builds) is implemented. Providing manual builds is not a high priority since changes are pretty frequent

Does not also require installing openseeface separately

Covered above, bundled application contains the the face tracker

Use https://github.com/chriskiehl/Gooey.git to make a gui for the python program https://github.com/emilianavt/OpenSeeFace

Not necessary. On windows this is handled automatically via the 'Start facetracker' button. #7 covers running the corresponding python command on mac/linux. It's not difficult to implement but I primarily use Windows 10 as my dev environment

Overall, I do agree the first time user experience is lacking due to a few lingering bugs

• [x] Face tracking offsets are not set correctly when the model is first loaded. This causes the model to basically fold in half until offsets are set by the user
• [x] Random crashes with no logs when the application regains focus, probably due to cpu usage? (Windows 10)
• [x] Settings are only applied when the 'Apply properties' button is pressed, which is somewhat unexpected

[you-win]

Probably closed by #34
