Merge branch 'Story71_TackAndGybeSmoothly' into 'develop'

Story 71 Tack/Gybe, Story 65 VMG Autopilot

# Implementation
- Added autopilot functionality to move boat towards a given heading with a single function call.
- Added functionality to move boat from one side of the wind to the other (tack/gybe) with a single button press.
- Added functionality to move boat to correct VMG from polars with single button press.
- Pressing a button a second time will disable the autopilot, as will pressing the Upwind/Downwind keys.

# Testing
- Fairly simple JUnit testing for a set of beginning headings and expected ends for the autopilot
- Unsure how cucumber testing would actually be better than simple junit testing in this case.
