Moves apply defaults settings to Board Setup (where they were
duplicated anyway due to an earlier botched merge).
Modifies the apply-to-graphics algorithm to skip copper shapes.
Modifies DRC library check to skip STROKE_PARAMS for non-copper
shapes.
Also moves the settings from Board Setup to Preferences > PCB Editor.
Also collapses Track Drag Mode from radio buttons to a choice menu to
save space and allow it to be with the other editing action modes.
