Add more jumpers for Teensy++ 2.0 compat

This avoids requiring folks to pull pins out of headers for Teensy++ 2.0
compatibility, instead just requiring them to cut the traces, which I
think is better and more importantly is reversible, so that if someone
builds with a Teensy++ 2.0 and then wants to replace it with a 3.6, they
can just re-close the new jumpers, desolder the old ones, and be good to
go.

Update to the new project file format (#47)

I opened and saved the project and its schematic, PCB, etc. Some got
saved with a different file name extension.

`kinx-cache.lib` had to been renamed to `kint-cache.lib` otherwise the
Schematic editor would complain that the file is missing. Then I
removed it as I was told in the IRC channel that after saving the
schematic in the new format, the symbols will be embedded and it's no
longer needed.

When opening the PCB there was a warning:
> If the zones on this board are refilled the Copper Edge Clearance
> setting will be used (see Board Setup > Design Rules > Constraints).
> This may result in different fills from previous KiCad versions which
> used the line thicknesses of the board boundary on the Edge Cuts
> layer.

The File > Board Setup > Design Rules > Constraints > Copper Edge
Clearance is 0.05mm. Clicking the board boundary belonging to the Edge
Cuts layer reveals a properties dialog with Line Width 0.05mm.
Being the same, nothing should change at the next refill.

The `.gitignore` file has been updated from its original source.

connect GND3 (Teensy vertical pin header) to GND

This removes the unexpected opens from the design.

Widen slots for compatibility with Aisler (#31)

Aisler is a board service that introduced a budget service for "Simple"
boards. KinT almost met the requirements, but these slots were too
narrow. These zigzags make it so that the slots are always 2.4mm wide,
but should still contact the posts and stabilize the board.

fixes #27

adjust silkscreen, route traces to enable GND plane filling
