Pixel Navbar, reverse engineered from smali.

Notes:
- This is forcing the Pixel Home button on people,
  and it looks ugly with the other nav buttons being hollow

- There MAY still be a few fixes yet to be found in this code
  because it WAS a big file to RE from smali. I have yet to find
  any, but time is the best tester.

- Shoutout to @bigrushdog for providing a decompiled form used
  to verify the smali and as a guideline for the more obsure
  smali sections. It was a big help.

- Tagging myself here to see adoption rate. @USA-RedDragon
