Replace the "ok" in M280, M301, M304, M851 with output not including an "ok"
to avoid senting two "ok"s for a single g-code.

Doing the same for M105 would break the input filters of the hosts.
For M105 the other "ok" is omitted.

Instead of changing SDEXTRASLOW variable to a slower speed,  the new
SDULTRASLOW is used for rigidbot panel.

Forgot Z2_MIN_PIN

• Removing trailing whitespace
• Adjusting indention for better readability
• Removing duplicated entries

Caveat Emptor —- 
I’m not sure that this really makes sense,
but why keep someone from using it?

For some reason that I cannot determine, using a sub-function causes
the Tune sub-menu to act strangely, yet replacing the function call
with its code content works perfectly.

Make the output of M105 more similar to Repetier.
Make the text-print pert of M105 an extra function to make it reusable. `print_heaterstates()`
Use `print_heaterstates()` in M019, M190 and M303

st_set_position takes long
```void st_set_position(const long& x, const long& y, const long& z, const long& e)```

anything is long, we don't need float there

dx -> dsx
dy -> dsy
dz -> dsz
de -> dse

by alternate definition for the callback macros

Move slow_buttons_update into the LCD_UPDATE_INTERVAL block
lcd_implementation_read_slow_buttons() will then be executed ~10 times a
second.

This is a back port of the correct in issue #248

Restore the Babystep Multiplicator functionality and now it's available
for X/Y/Z

For now Z_MIN_PROBE_REPEATABILITY_TEST is not possible for DELTA or SCARA
configurations.
This PR comments the feature out, where it is commented in by default.

because of hardware differences on the SERVO0_PIN

Tests DELTA, AUTO_BED_LEVELING_FEATURE and ALLEN_KEY

According to #123 negative values for XY at or below -100 are displaying incorrectly, dropping the first digit. Deltas can easily have XY values in this range. This PR adds a function to display floats/ints formatted like `_123`, `-123`, `_-12`, or `__-1` as appropriate and applies it to the XY coordinates on Hitachi displays. It also moves the Z value to the right to be consistent with the XY formatting.
