Tweak the documentation

This reverts commit e6cb8ee188.

Conflicts:
	Marlin/dogm_lcd_implementation.h
Confilkt solved
Needs rework.

This reverts commit 8c5bb38748.

by shifting things some pixels around

- Pass selected state directly to lcd_implementation_mark_as_selected
- Rename sel function parameter
- Include a minor fix for SdBaseFile.h

with sources in /fonts

in dogm_lcd_implementation.h
by using standard font and
shifting down temperature displays by one pixel
Saves 2300 bytes.

- Compare pr_char to space
- Fewer calls to lcd_strlen

- Get rid of _selected functions, passing selected state instead

- Add BIT and TEST macros
- 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

Automatic selection was to unflexible.

Updated documentation

Updated language files to new logic and documentation.

Updated bdf2u8g.exe

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.

The encrot values are used in only one place, and don’t vary, so remove
redundant references.

Introduced lcd_strlen() and lcd_strlen_P().
Replaced the old functions where necessary.
Reworked language_ru.h.

Speeded up test for zero length string in cardreader.cpp

I've insert the define and pointer entries for the Viki 2 and miniViki
from Panucatt in all of the example configs and main config. With these
additions and with pins done in the old single pin.h style...I was able
to get the display working fine save for needing to turn Delta Segments
per Second down. But that's a common graphics lcd issue being looked
into right now.

I need assistance in understanding how the new divided pins files fit
together because my previous attempts at trying to get it to work
appropriately didn't seem successful. This originally came from trying
to find out how to swap the XYZ Min and Max Endstop pins in the Azteeg
X3 Pro. It only comes with one set of connectors and they're Min
Endstops. My previous experience didn't turn out well trying to tell the
firmware to home to the Min Endstops so the best solution I found was to
swap the pins in the firmware. If I'm missing a conflict with a setup
other than delta please let me know, but it makes sense in my setup.

- Display fan speed 0-1 as “—“ and 254-255 as “100%”.
- Display 4th extruder instead of the heated bed

New function now drops the prechar (select character) and makes the first
column usable for text.
Marking the line is now constantly made by highlighting (reverse).

Replaced selection code in:
lcd_implementation_drawmenu_generic()
_drawmenu_setting_edit_generic()
_drawmenu_sd()

with new function.

Combine 1/(rows+1) with u8g.getHeight() to get rowHeight and just use
that.

Prework for issue #1448 and #1447

Will merge in when pull request #1457 is in.

Replaced calculation to centre bitmap with fixed values.
Saved 20 bytes.

and win another 1694 bytes.

No visible impact.

Small changes (and formatting to confuse the diff’er) which first
allows DOGLCD and LCD_PROGRESS_BAR to be enabled in tandem, then a
#warning (rather than error) that the extra progress bar / message
options don’t apply to graphical displays at this time. This leaves
open perhaps combining the progress bar and message area in some future
(or forked custom) graphical LCD display arrangement (at which time the
relevant variables may be moved into ultralcd.cpp with externs in
ultralcd.h). I also added a conditional error that the progress bar and
the filament display may not work well together.

new version is pretty generic and should work in most scenarios

logo is now 110 pixels wide and starts 9 pixels in from top left corner and also 9 pixels down from same corner... this will give a 9 pixel border all way round

ver info is placed centered and there is a 9 pixel from bottom of display to ver info

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

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.

Breaking up languages.h makes it easier to translate. Using language
codes makes it easier to select a language and sets the naming standard.

Here comes a compile-time operation to match the extruder symbols on the
info screen to the set number of extruders in configuration.h.
When only one extruder is selected, the "1" on the symbol will not be
displayed.

Added support to show the filament width on the status line of the
graphic LCD.  The status will show for 5 sec and then switch over to
data.  Status can be seen by clicking the button.

#elsif does not exist #elif is correct
