Allow partial screen version of energy graphs

Allow a half or one third screen size version of the energy graphs page, similar to how the music page has a half screen mode. 

It's nice sometimes to be able to monitor the energy usage while still being able to see the map.

While in partial screen mode, remove all the buttons (to save space), and allow swiping left/right to switch between consumption and trip graphs.
