Add info page selected by steering wheel eventicefish_8.99.5icefish/8.99.58.99.5

Add a information window that can be switched to based on the
"event.info" event from signal composer that the steering wheel
"Info" button results in. For now, it simply displays the vehicle
and engine speed in numeric form in a larger font, and a small
time display. The speeds are also driven by the corresponding
signal composer events that are hooked to the underlying CAN
messages.
