Hook burst controller to the shutter button long press.
Hooks up the shutter button long press to start the burst.

saves results when burst is complete.
The burst eviction handler is now installed on the ring buffer

The ring buffer is cleared before starting and after completion of the
burst.
Also provides a stub implementation of the BurstController that has a
static method which controls if burst is enabled or not.
