loginmanager: Import Hawaii.Components

NoiseBackground was moved there.
loginmanager: Don't try to set icon theme

It doesn't work.
lookandfeel: Create login screen as item

So that we can invoke setErrorMessage() or setInfoMessage()
lookadnfeel: Remove lookandfeel_ prefix in i18nd

The package name is enough.
lookandfeel: Add an id to ShutdownButtons

So that we can trigger signals when a button is clicked.
lockscreen: Show power off button when kscreenlocker says so
loginamanger: Default theme configuration

Set icon and cursor themes from configuration.
This works with latest SDDM master.
lookandfeel: Remove svg icons

We can finally use the maui icon theme even from SDDM, so we don't need
to ship a copy of the icons ourselves.
lookandfeel: Don't install dummydata into SDDM theme
lookandfeel: Heuristic to replace default SDDM face with icon

Assume that SDDM default face is the same as not having a user icon
at all and use an icon from the XDG icon theme.
lookandfeel: Set the correct color in user delegates
loginmanager: Directly use sddm

Don't pass sddm object, it's a context property.
loginmanager: Don't accept mouse events just to change the cursor

Don't accept any button so that MouseArea will only change the cursor.
