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.

503 fwretract dev branch

- Fixed issue when BAL area probing is shorter than it should be for
grid probing
- Warning when BAL activated with Delta Kinematics
- Fix XY_TRAVEL_SPEED when homing Z axis

Consider negative Z Offsets when auto bed leveling is active

Fixed BABYSTEPPING feature

Fixes #1069.  Added "auto fan" checks to PID_autotune.

 temperature.cpp: Add Conditional Integration to prevent excessive integral windup

Move initialization of errormagic[] and echomagic[] to Marlin_main.cpp

LCD Progress Bar

Current defaults are all 255.  If it makes sense to reduce them, they should come down together, and
be in a  PID_INTEGRAL_DRIVE_MAX <= PID_MAX <- BANG_MAX relationship.
