WIP: Dark theme for Windows (for real this time)
Still a little WIP.
Dark theme patch for Windows that does not use the Fusion theme. Used colors from Windows Explorer as a reference. Almost all the appearance is defined in a QSS file.
Known issues for now:
- The tab labels are not centered vertically on the device list (marked dark-red)
- QRadioButton's require custom drawn images, can't do them myself
- QSlider is not yet configured
- No smooth animations, I don't know if QSS supports them
- Title bar can not be configured yet
- Scrollbars can not be properly configured
- Progressbar would lose it's animation if configured it to dark theme, so I had to leave it light
