stonyman.v subtracts a constant val from each px

stonyman.v now processes incoming pixels, adjusting them to fit the
desired out width, and scaling them down.  Pixels which wrap at the
large end are not properly clipped however.

stonyman_apb3.v has a minor change for clarity.

the TOPLEVEL smartdesign was changed to use cam1_inphi.
tp_cam0_startcap was removed to accomodate this.
fixed ADC pin swap bug in stonyman-imager-board

I had switched pin 1 with pin 3, the positive supply and analog in pins

board.
