[evolution/webkit-composer: 24/111] Make font-size change work



commit 3b3ea23fd55758b4506128af5ee9881520732d1b

    Make font-size change work
    
    The 'current-value' property of font-size action group
    is binded to 'font-size' property of EEditorSelection,
    so toggling the action and change of current value when
    selection changes is all automatic.
