Photon Colors di damagnat

This is a simple theme that brings the Photon colors (they are used from version 57 to 88 on Windows 10 and macOS) with the dark blue tab background to Windows 7, Linux and the new Proton theme.

Tip: To turn off the gray title bar on Linux, right-click on the title bar and then click "Customize". Then look for the "Title bar" option at the very bottom and turn it off.
