Fixed DRC errors in reduced switching board

Preparing Julian's version of Scoutfly to ship out. Fixed a bunch of DRC
errors, but there are still a few. Nothing major. Just some spacing and
routing angle errors.

Made changes that Abe recommended:
Fixed SHDN pin connection.
Changed inverter voltage level from 5V to 3.3V.
Modified PB Controller to have value displayed.
TODO: Address concerns about shutdown timing and switch power loss.

Added a new push button controller circuit. Uses new IC instead of solid state machine because there was no room for solid state machine circuit. Preformed changes that Abe recommended. Routed new circuits. Board should be ready to send back out to kwoo.

Added new switching power supply for 5V and 3.3V supplies. Routed board to include these, and switch.

Added packages to kwoo for diode, dd2pak for switching regulator and switch. Working on schematic for the new power system using switching regulator.
