Night Color adjusts the color temperature based on the current time in
your location. It's not a generic color correction module per se.
We need a central component that can be used by both night color and
colord integration to tweak gamma ramps and which will be able to
resolve conflicts between the two. The Night Color manager cannot be
such a thing because of its very specific usecase.
This change converts Night Color into a plugin to prepare some space for
such a component.
The tricky part is that the dbus api of Night Color has "ColorCorrect"
in its name. I'm afraid we cannot do that much about it without breaking
API compatibility.
Setting the ApplicationDomain to kwin, both use the kwin catalog.
The left-over code for catalogs is removed. Note for adjustments:
* scripting doesn't provide an own catalog
* scripts are extracted but there are no scripts with i18n
Messages from kdecorations library are extracted to libkdecorations.pot.
Messages from kwineffects library are extracted to libkwineffects.pot.
Currently there are no messages yet in kwineffects, so it's for future use.
