    stylescheme: raise priority of .current-line-number CSS
    
    When using GTK CSS to set the background of the current line number, we
    need to elevate the priority so that it takes precedence over the normal
    background color styling.
    
    This now uses "textview .current-line-number" which appears to be enough
    to raise the priority.
    
    Fixes #53
