Get it while it's hot!

Finally, a hand-solderable Sink that doesn't need rework! The output circuit has been fixed, so no cutting traces and point-to-point wiring should be necessary.

Other changes:

• D1 is surface-mount, and no longer considered optional
• P1 extends further off the board edge
• SW1 and J1 don't extend off the board edge at all
• SW1 doesn't need to be installed for the device to work
• All the footprints have been updated to the latest KiCAD footprints
• The high current traces are wider, to the point where making these boards with 1 oz copper isn't out of the question.

All the schematic changes have already been tested, so v0.2 should be ready for use. However, this is considered a pre-release because it isn't really meant to be sent to a PCBA house yet.
