Add KDE support for scale factor

[precla]

As the title says :)

is char (g, k, ... ) ok?

Sorry for the delay, I'm currently not getting much time for my open source projects. I think we should use an enum for that with KDE, Gnome and Unknown values. Also, the logic now that I look at it seem to be wrong in this place, we should exract this method into some helper class that can be reused. If you want I can do this change.

Indeed, enum sounds better.
You mean the logic inside getScaleFactor?

[DamirPorobic]

I mean the logic in getLinuxDesktopEnvironment

i can't wrap my head around making a helper function :D

i'd be glad if you take over :)
