Fix lcd_status_message

Disable splash-screen when done once

Azteeg X3 Pro Pin fix ups

Update Configurator Files

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`

Fix compile error with Z_DUAL_ENDSTOPS

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.

Have the configurator read from MarlinFirmware repo

Execute DOGM display-loop less often

Fixed scara directions

Config said for a delta instead of for a scara

Fix bad thermal runaway trigger

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.
