Enable high-DPI scaling to support 4k screens.

Browse Source 
This enables coordinate system scaling for high-DPI
displays, which enforces correct proportions even
on small 4k displays. The icons are scaled up without
interpolation, which makes them crisp, but a bit
pixelated. A new scalable icon set will solve this
problem, but is not scope of this patch.

Resolves #548, #1381, #1710, #1888

In addition, this patch enforces the KeePassXC icon
theme for the KMessageBox close icon, since using
the system theme produces very ugly icons on some
Linux systems.
