Added Factory Style LED Controls (#2678)

Added Factory Style LED Controls (#2678)

* This adds a keymap to the MF68 labeled factory.  It is an attempt to mimic the layout on the factory keycaps of the non-backlit board.

There are some small differences:

1) FN+WASD are an arrow cluster
2) FN+Z (Start media player) and FN+] (Start Calculator) are not mapped
3) FN+GHJKL are Backlight controls
4) An FN2 layer exists for future growth
5) The CAPS key is maped as FN2, for CAPS Lock use FN+CAPS

* Changed the CAPS key to be CAPS Lock on short press, FN2 on hold

Added LED controls to FN+Arrow Keys to better mimic factory backlit boards.
