bitsy0.3a: Changed C35 to be 100n decoupling cap.

Minor cleanups, finishing up for prototype order. This is the status from the ad hoc stream from Apr 4th 2020.

Some routing and silkscreen cleanup.

First routing pass finished. This is the status after the KiCad Let's Play stream from Apr 02nd 2020.

Updated the oscillator footprint and initial routing/cleanup work. This is the status after the KiCad Let's Play Twitch stream from Apr 01 2020.

Finished circuit changes todo items. * Replaced the VPP2V5 circuit with just a jumper. * Added missing 3d models to the footprints. * Replaced MEMS oscillator with a more common type. (might not be final) This is the work done during the KiCad Let's play stream on March 29th 2020.

Replaced/added the null logo to the boards.

Initial commit of icebitsy v0.3. This is the status after the last stream on March 26th 2020.
