changes for r1.005 board revision

Updated scroll wheel design to increase reliability.

adjusted scroller array size to prevent int overflow errors when diodes give higher values

added wedge

altered wheels to have 13 holes instead of 20

Design files, gerbers and schematics for R1.004 boards. Updated from R1.003.

Small fixes for the roller dowel and primary buttons that address manufacturing issues. Changes improve probability that part will print properly.

Cleanup, removing deprecated STEP files from old version.

scroll wheel is now done with a stochastic algorithm to make up for the inherent noise in the phototransistor

Constrain ANGLE_TUNE setting
