Subject: [PATCH] Add shortcut to toggle Strava layer

Press 'S' to show the Strava buttons (if the API key has been set) as
well as the Strava segments layer (once it has been fetched).

Note that fetching and updating data from Strava still needs to be
triggered manually by clicking the respective biking or running button.
