Subject: [PATCH] gui/views/week-view: Add shortcuts for zooming in/out

It's possible to change the density of the week view, but only through
pinch-zooming or Ctrl+scroll wheel. This means it can't be done with
only the keyboard, and since neither of these methods are documented,
it's not discoverable either.

This adds shortcuts for zooming the view in and out, and documents them
in the shortcuts dialog to make them discoverable.

Helps #1556
