- Address issue raised in #1961

Remove set-coordinate extension of G28

Max endstopp

Macro steppercpp

delete some tabs

Include axis parameter to ultralcd's line_to_current

Fix homing of YZ with DUAL_X_CARRIAGE

Fix for #1946

Add DISPLAY_CHARSET_HD44780_CYRILLIC as alternative in SanityCheck.h

More Beeper clean up

Add M410 QuickStop command

c'n'p ftw :/

and add some documentation - how to integrate a new font.

Syntax error.

no user will home to 0 with a max endstopp

and removed some tabs.

Centralised beep code to lcd_buzz().
From gcode_M300() and lcd_quick_feedback().

Enforced max. duration for M300 to 5 seconds.

Corrected description in 'Configuration.h'

LCD_FEEDBACK_FREQUENCY_HZ 0 gives now a silent delay of
LCD_FEEDBACK_FREQUENCY_DURATION_MS.

Corrected wrong order of parameters.

Fixed compilation error "error: stray ‘\357’ in program"

Added new PID autotune info, to make easy copy & paste results to marlin

Fixed jump in speed at high accelerations on axes with lots of steps

Introduced in commit 697ee2dc and later spread to other files.

I.e., when acceleration * steps per mm > 2,000,000.
This was done by changing MultiU24X24toH16 to take a 32b bit operand.
Removed the claim that stepper.cpp uses the Leib algorithm.

Babystep delay 2us

Fixed M48 mismatch between n and P parameter on documentation
