This commit add comments describing tui_ui_out and its fields, and
cleans up the code a little bit.
Also switch to using in-class initialization so that the initial
values can be seen alongside the comments.
I see no reason for initializing m_line as -1 instead of 0, since all
the checks in the .c file are of the form "> 0". AFAICS there's no
practical difference between -1 and 0. So it seems simpler to
initialize it as 0.
There's a bit of redundancy in tui_ui_out::do_field_string, which is
fixed by this commit.
