Squished #1849

- Set `de` to 0 when `position[E] = target[E]`
- Address regression mention in #1846

- Sections in all `Configuration_adv.h`
- Recognize JAPANESE/WESTERN/CYRILLIC options
- Better capturing of comments for tooltips

- Address Issue #1682 at hash #issuecomment-89756858

Because we now can use utf8 with up to 3 bytes per symbol,
lcd_status_message[] must be 3*LCD_WIDTH wide.
Filling up the message, or cutting to length, are fixed to.

Fix for #1832 about at the end.

Should be `retracting` and not `retract`

Just and only display splashscreen only once.

This reverts commit bf04a92cc0.

This commit checks whether or not HEATER_0 is in use, and if not, skips
the MIN / MAX temperature checks.

Example for splash screen.

Splash screen was shown with every display init.
That means every time the menus where entered.

Note the 2 in the initialisation.
The buffer is already written in two steps a 512 byte.
Without the 2 only the upper half is shown.

Config said for a delta instead of for a scara

In 'if (encoderPastThreshold || LCD_CLICKED)' lcdDrawUpdate was not set.

'lcd_status_update_delay'-loop was not effective in  function
lcd_status_screen().
The loop prevented the update of the status screen but not the displays
update.
Shifted the loop into lcd_update().

This reverts commit 6361404b91.

Shifted condition should still be in.

Dot is moving not so fast -> less executed loops.

Result see: https://www.youtube.com/watch?v=tdu7J0i-c4g
Loop is executed several times per display update.

- Document `manage_inactivity` function
- Allow `EXTRUDER_RUNOUT_PREVENT` to work with all extruders
- Use faster `memcpy` for copying coordinates

Just a simple #ifdef Z_PROBE_ENDSTOP to define the pin for it. Also has
a couple commented lines for switching Z_MIN_PIN if needed.

It wouldn't compile because of this line in temperature.cpp it turns out
it was just a stray ( that didn't line up with the previous lines so I
just made it in line with the rest and it compiled fine.
