Hi, Joe.  Thanks for updating this utility.  I haven't tried it out yet but
the screenshot looks nice.  It's starting to seem like time for another
release, so I'll see about putting it in.

One concern I have here is that sometimes the peripheral does its own
scrolling when the message is too big for the actual LCD.  If your display
is smaller and you're trying to do your own scrolling as well, then it might
not be too pretty.  I'm not sure what the best way would be to figure out
how large to make the display, but perhaps you could make it grow
dynamically whenever you got back a string with more printable (non-null,
non-space) characters than you already had room for.  Since I'm not familiar
with QT I don't know how hard this would be.

I think after 0.9 I'll just go to 0.10, where the dot is merely a field
separator rather than a decimal point in the true mathematical sense (in
other words, 0.1 != 0.10).  I don't see any point in retroactively applying
leading zeroes to the right-hand side of old versions.
