[STUMP] Windowlist completion

[Rodrigo Lazo]

Hi everybody,

I've been using stumpwm for a couple of weeks now and it's awesome,
great work!!

Now, windowlist command tries to match what I type with a window name,
which is great, except that it has two problems:

* `j` and `k` move-up and move-down the list, which is confusing.

* Pressing Backspace inserts a `?` char, instead of deleting the
  preceding char.

Fix for the backspace is pretty simple, at least in the way I've done it
(not sure if it's the right way, though). Given that matching is
supported and it's very useful, I'm puzzled by the choice of binding j and
k, because, altough it allow easier browsing, it defeats the whole matching
idea. It wouldn't be better to just delete those?

Thanks!
