[evolution/webkit: 59/196] Add EM_FORMAT_HANDLER_COMPOUND_TYPE flag to EMFormatHandler

[Dan VrÃtil <dvratil src gnome org>]

commit be660262c1594bc1eb3e6d48e99d0f4011882d14

    Add EM_FORMAT_HANDLER_COMPOUND_TYPE flag to EMFormatHandler
    
    This flag says, that the particular mime type is compound
    (application/mbox, message/rfc822) and that we should attempt
    to parse it even though it's an attachment
