[evolution/wip/webkit-composer] Hide insensitive paragraph styles in the Plain Text mode

[Milan Crha <mcrha src gnome org>]

commit c052e6bf80ede1466c6c4eee36fbf13850f7dde2

    Hide insensitive paragraph styles in the Plain Text mode
    
    Instead of showing a complete list of paragraph styles with some
    insensitive in the Plain Text mode, hide those insensitive completely.
    It makes the UI nicer and doesn't confuse users with options, which
    are not applicable in the Plain Text mode, the same way as the HTML
    toolbar is hidden.
