feat(konsole): konsole plugin with fullscreen and profile switch

[ekorchmar]

Description

Adds Zen mode integration to Konsole, making it fullscreen and (possibly) changing to a different pre-configured profile using qdbus.

I wish I could find a way to change font size or background opacity rather than switching profiles dynamically, but I could not find a way.
