- Add 3 new lines to `pins.h` to remove 2 redundant tests in
`pins_RAMPS_13.h`

Moved SDCARDDETECTINVERTED and SDSLOW to Conditionals.h.
Added U8GLIB_LM6059_AF to define display specific actions.
Added reminder to compile in u8glib

Rename of define to avoid confusion between the controller and the
display which had similar names.

Fixes for some code formatting changes and commenting out the
ADAFRUIT_ST7565 define that was left defined.

Added support for new display type

Created a new board to make using RAMPS as a CNC machine controller
easier. It maps pin 8 to the spindle and pin 9 to the controller fan.

Updated documentation in Configuration.h.
Cleaned up and commented some code relating to Z_PROBE_ENDSTOP.
Separated Z_MIN_ENDSTOP and Z_PROBE_ENDSTOP completely.

Confirmed Sanity checks are working.....

Code cleanup for Z_PROBE_AND_ENDSTOP.
Added Z_PROBE_PIN to pins_RAMPS_13.h

Typo fixes in comments in existing code.

With this change a mechanical or optical switch may be used to check the
availability of the filament and when the filament runs out an M600
(filament change) command is issued. This is only done while printing
with an SD card.

This feature was requested several times (issue #679), but the requests
were not accepted since it was believed that this situation should be
handled at host side. However during an SD print the control is totally
on firmware and I think that during an SD print it should be handled by
the firmware.

The original code was posted at reprap forum
(http://forums.reprap.org/read.php?1,297350) by Lazymonk. I have only
corrected some bugs of the code and improved it by adding definitions to
the configuration.h in order to make it more standardized.

- Also apply cleanup for #1514

Hopefully this is helpful to organization and future expansion….
