    sourceview: Delay settings init to realize for theme lookup changes
    
    We're about to want to initialise a MeldSourceView when doing colour
    lookups for themes, which fails on infinite recursion currently. The
    easiest (and technically probably correct) way of fixing this is to
    delay the settings initialisation in the widget until we actually hit
    the realize hook.
