[polari/wip/fmuellner/nickserv: 3/4] room: Add method to send "identify" messages

[Florian Müllner <fmuellner src gnome org>]

commit fcff3a7b6ea96b8587c1f0df3825545693609e1f

    room: Add method to send "identify" messages
    
    The method is a thin wrapper around tp_text_channel_send_message_async()
    which doesn't add much convenience, but it allows us to differentiate
    between the "identify" messages sent by the user and the ones we send
    automatically, so that we don't ask the user whether to save the saved
    password again ...
