- Add _APPLY_ macros to stepper.cpp to help with consolidation
- Consolidate code in stepper.cpp using macros
- Apply standards in stepper.cpp
- Use >= 0 instead of > -1 as a better semantic
- Replace DUAL_Y_CARRIAGE with Y_DUAL_STEPPER_DRIVERS

Cleaned typo in language_test.h Cyrillic part.

Latest upstream

Fix missing temp_error declarations

- Fix for #1591 replacing #1595

short:
this script scans the first few lines from a gcode. If the line between 2 different z are greater than min_g1 this is our first layer. On this layer we search the min and max values of X and Y. With an offset we write that in a new file.

Conflicts:
	Marlin/Configuration.h

Macro indirection for stepper drivers + Support for TMC26X and L6470 Stepper Drivers

update

Improve description in Configuration.h

The max acceleration limiting was in wrong place.

Added option to set Travel Acceleration (non printing moves).
The M204 options was a non sense (S for printing moves and T for retract
moves).

It has been changed to:
P = Printing moves
R = Retract only (no X, Y, Z) moves
T = Travel (non
printing) moves

I will add this info o G-Code wiki in reprap.org. I also advise to put
this info in Marlin next version changelog.

I forgot to enclousure the variable with #ifdef

- Decide what output function is to use.
- Precautions. If non of the DISPLAY_CHARSET_HD44780's is selected fall back to Japanese.
- When we are not on the dogms setup a mapping table depending on display type and mapper.
- If we are on dogm we use ONE To ONE mapping - except kanji.
- select and define one of the mapping functions.

And made falback to kana work.

removed the link as the software i had did not work, nor does anyone hardly use irc chat but just hang out there

Top -> down
- We don't need the old Marlion_font package any more - we made new.
- But we need information about configured fonts and the mappers.
- We support Cyrillic now.
- LCD_CLASS is not used in this file. LiquidCrystalRus.h is deleted anyway.
- define some fonts
- BIG_EDIT_FONT works only together with western languages.
- Select a matching FONT for the MENUE depending on the defined language.
- Number the different font-types. Wanted to avoid to store complete font-structures when changing fonts back and forth.
- Marlin special symbols are now at the lower end - like in 'ultralcd_implementation_hitachi_HD44780.h'
- insert the new remembering setFont function.
- insert the new counting lcd_print functions.
- make use of the new setFont and lcd_print functions.
- On some places redefined one character long strings with chars to avoid overhead and reduce warnings.
