Winner-mode keeps a history of window configurations. Handy when magit

By default, if you a region selected and hit "backspace" it does not
actually delete the region, which is weird to me. This changes that
behavior.

Cycling forward or backward one buffer is handy when using slighty
more buffers than windows, but helm buffers (and others) can really
add a lot of unhelpful buffers. Instead, filter out "boring" buffers.
