add a pick quit keybind (#432)

The last time[0] this was discussed, no-one was against it but no-one
was confident in it either and so it was added to nsxiv-extra as a
patch.

But now that enough time has passed, it seems like there's a pretty high
demand for something like this because there's plenty of use-cases that
use nsxiv as a "picker" where it's meant to quickly pick a single file.

And so add this as a convenient default key-bind.
