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

Fix status LEDs update when reinitializing the display

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.

Align strings with release

in language.h, but was not renamed here. If TEMP_SENSOR_1 is enabled as redundant then
an error is thrown that MSG_EXTRUDER_SWITCHED_OFF is not defined.

Keep "astyled" reformatting

As noted by @darkjavi et.al. in #103, the E1 motor was not being enabled in planner.cpp when using DUAL_X_CARRIAGE. This patch enables and disables E1 as it should.
