[feature] BIG Commit - Better UI, VHS recording speed, noise seed and…

… overall code cleanups

This commit changes the overall code and UI. Most of the changes based on the pull request
on the original ntscQT by valadaptive. This includes:

- New feature: Noise seed (which allows you to set a seed for all video effects)
- New feature: VHS recording speed switch (SP, LP and EP)
- A better UI, overall
- Code cleanups

You can find more about these changes on his original pull request:
JargeZ/ntscqt#94

Other change, this time outside of the pull, is the logo which is now in
the topleft corner of the UI.

- Logo on topleft UI

Thanks to valadaptive for the changes.
