Move and extend axis_unhomed test to deploy/stow_z_probe().
Move and extend position store/restore to deploy/stow_z_probe().
Now all kinds of probes can use the 'E' parameter in G29/M48.
Allen key probes can be used now for grid and 3-point levelling.
Deploying the Allen Key probe uses big moves in z direction.
Too dangerous for an unhomed z-axis.
Throw a compile time error when we try to configure an
Allen Key probe homing to z-min and having no other z-min-endstop.
The `PROBE_IS_TRIGGERED_WHEN_STOWED_TEST` is able to detect if a probe is
successfully deployed/stowed.
It was part of the Allen Key probes code only.
Now the function is generally available.
Currently this test is compulsory for Allen Key probes to not alter the used behaviour
If you want to add the test for an other type of probe simply add
```
#define PROBE_IS_TRIGGERED_WHEN_STOWED_TEST
```
to your config.
Supports both dual and single head printers (with the correct config).
Includes community sourced feed rate fix.
Rename / move files.
Remove redundant definitions.
Includes:
*firmware version / branch / date.
*extruder count
*board information (name, serial details, power supply type)
*thermistors (names, min/max temperatures)
*printer statistics (PRINTCOUNTER details)
Thanks to @thinkyhead for contributions.
If Z_RAISE_BETWEEN_PROBINGS is null or undefined the probe is currently not raised by home_offset[Z_AXIS] and zprobe_zoffset.
But when different from 0 is.
If an undefined Z_RAISE_BETWEEN_PROBINGS expands to 0 (and it does) this is the solution.
A similar asymmetry exists with the newly introduced 'short-cut' in G28 - but its the rise before anything is probed - so should not make a difference.
