Balsa information window

[Peter Bloomfield <PeterBloomfield bellsouth net>]

The information window has been mentioned as being broken wrt 
wrapping.  This patch (to current cvs, but probably to most 2.0.x 
source trees) uses a GtkTextView widget instead of the current 
GtkTreeView--see how you like it!

The GtkTreeView was used only because it's the logical successor to 
GtkCList, which was used before, and...oh, well...
