Design mismatches

[cmkohnen]

I've stumbled across a few inconsistencies in contrast to default Libadwaita behaviour:

• When deselected the knob of switches should have the colour #d2d2d2 instead of #ffffff (Game properties)
• When hovering over a switch in deselected state, the colour should be #636363 instead of #4e4e4e (Game properties)
• The container should have the colour #363636 instead of #3a3a3a (Game properties)
• On hover the container should have the colour #3c3c3c instead of #454545 (Game properties)
• The hover effect in settings doesn't match:
  
• In general the mouse pointer should't change to the hand when hovering over clickable buttons, dropdowns, etc.
• Dropdowns in Game properties should activate when clicking the container. The container should also receive a hover effect.
• This should be connected:
  
• The Headerbar is misaligned and for some reason hoverable:
  
• (probably) all popout windows are missing a frame

Should mostly be fixed in v2.0.
