CURA-5821
The original implementation that refreshes a QImage seems to cause
memory overflow on MacOSX and Windows. This is a different
implementation. It doesn't cause memory overflow, but it does consume a
lot of CPU power.
Now with unified style as agreed upon by Simon & Ian.
Rules:
- ID before all other props.
- All props before children.
- All props after ID in alphabetical order.
- Empty line between children.
- Semi-colons.
Note: I didn't touch the DiscoverUM3Action because that's it's whole own UI part.
