[kupfer: 43/51] ui: Hold a reference to the current GdkScreen

    ui: Hold a reference to the current GdkScreen
    
    A crashing bug in AsyncCommand (Send to Command...) bisected to the
    commit 'ui: Use uievents to open and close displays'. Unknown why, we
    need to keep a reference to the GdkScreen we are using to avoid the
    crash.
    
    Thanks to git bisect.
