fixed minor power PCB problems

Fixed several issues with the power PCB.

  - fuse holder
    - increased inner diameter to fix tight fit
    - increased outer diameter to increase pad surface
  - switched terminal connector with larger hole size
    - 1.25 -> 1.54 mm
  - fixed size for C2 and C4 capacitors

Added a bill of materials that can be uploaded to Digi-Key
or anywhere else to get a listing of parts.
