Due to the fix for #1248, X and Y probe offsets must not be floats.

Add Filament menu and add Filament/Retract settings to config store.

Fix typo, PID_BED_POWER -> MAX_BED_POWER

temperature.cpp: Fix typo of MAX_BED_PID to MAX_BED_POWER.

The compiler does not support comparing float values: "error: floating constant in preprocessor expression"
The loss in X/Y precision shouldn't matter for Z probes, as most microswitches or inductive sensors are larger than 1mm square anyway.

MAX6675 Slave Select pin

Somehow the pin definitions for the MAX6675 Slave Select/Chip Select got changed back to the hardware SPI SS/CS.  
Pin 49 cannot be used as that is used by the SD card socket to detect if an SD card is present.
Pin 53 is the Hardware SPI SS, which is dedicated, nicely, to the SD card SS and therefore cannot be used as the MAX6675 SS
Pin 66 is in Aux2 port adjacent to the Hardware SPI interface port on RAMPS 1.4, and is currently not used for anything.

Fix regressions affecting compilation

Format Z like XY on LCD

This fixes two regressions, caused by #1167 and #1191 .

sp=space-padded, similar to: ns=no-sign

This is the optimal code for a self-contained formatter, although the
original code is crafty in being smaller and simpler, and can be
evaluated as using the original output as a scratch pad for state,
making the final formatter more straightforward. While this code is
longer, all code-paths are minimal.

Move delta calibration menu to sample delta configuration.

Turn off by default.

Logic error correction

Language Fix - Using the new language implementation wasn't behaving as expected.

Conflicts:
	Marlin/language.h

No matter what LANGUAGE_CHOICE was set to it would always take the en branch.
I revamped it a bit to use a macro to create the language include file name. This required a slight tweak to the RU declaration since it's special-cased in a couple places in code.

This is an attempt to pull my changes from #1222 over.

Delta manual calibration menu

To test/enable, uncomment the #define DELTA_CALIBRATION_MENU in Configuration.h

fixed minor typo

Expand manage_inactivity #1264

void manage_inactivity(bool ignore_stepper_queue=false)

standard is false so it is not necessary to change additional code. this
change should be better, hopefully nophead like this :)

change filament issue

more speaking name

make a more general solution

Merge branch 'SAV-MkI_merge' into Development

Tested for SAV MKI and SAV 3D LCD on lewihe.
