26.3.17

• Fixed build regressions from the mainwindow.cpp manager split so Qt 5.9 and lower
  build again on old build tooling (for #3509)
• Fixed a crash when closing the Settings dialog after canceling live dark mode or
  editor color schema changes, by updating the system tray icon through the tray
  manager instead of a stale pointer (for #3509)
