This adds a user switcher borrowing elements from the lock screen and log out dialog.
It will be used instead of KRunner as main UI for switching sessions. The sessions runner

CHANGLOG: The main user switcher UI has been completely re-designed

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
techbase wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.
