Fixed patch cable selection of whole / fractional number pos (#1550)

Fixed selection of patch cable decimal number pos for editing with the horizontal encoder

If automation view is the underlying root UI, it will only engage horizontal scrolling if you've reached the far left or far right edit pos for the decimal patch cable number

also disabled scrolling patch cable number if you're holding down horizontal encoder as it makes zooming in/out in automation view more cumbersome
