Routing complete, finalizing files

Moved some ADC pins around and cleaned up routing, was able to get this
down to a 2 layer PCB. Most of bottom layer is ground plane.
Had to change 0603 package to remove silk as silk to soldermask
clearance was annoying.
No DRC errors.
Generated drill table and eliminated a drill size for mounting stubs
under thermistor audio jacks.
Need to generate vendor files.
