/*
* This data structure purpose in life is to maintain a GtkTextBuffer
* with these properies:
*
* - The channel is not editable:
*
* - There is an area after channel area where the user can enter new
* messages
*
* - You can add messages, and they will be displayed in gray in the
* channel area.
*
* - You can /commit/ messages which means they will turn black
*
* - Messages will be added to the channel area in the order they
* are committed
*
* - The user displays as either
*
* - The users nickname, followed by a colon, followed by a space,
* followed by the text that the user has entered in a normal
* typeface
*
* or
*
* - The users nickname in italic, followed by a apsce, followed
* by the text the user has entered, in italics
*
* The first style is used for nomal messages, the second for
* 'third person messages', ie. 'ssp thinks blah blah .... '
* as opposed to 'ssp: blaah blah blah'
*
* The channel buffer also maintains a topic
*
