Z_PROBE_ENDSTOP

Incorporating Build Numbers

Fix typo in Marlin_main.cpp

Refer to http://git-scm.com/docs/gitignore
to see why this is appropriate

The automatic versioning system extracts a
build version number from the SCM system

That versioning information is written to the file
_Version.h, a file that is NOT preserved in the SCM.

If such a file will be present,
we include it here to utilize the parameters
that are defined therein.

related to current_position[Z_AXIS] and retract_zlift.

'+ =' -> '+='

Fix for #1786

- Add comments documenting `thermal_runaway_protection`
- Add an enum for the thermal runaway states
- Add macros for temperature helper functions
- Fix a glitch with the z probe sled in homeaxis

Catch unlikely but possible error and head crash when using
Z_PROBE_REPEATABILITY_TEST

Fix MIN&MAX temperatures again

old bump_divisor for cartesian/corexy-printer

is not used.

some people are starting to ask why homing is so slow. this is the old standard hard-coded value.

Conflicts:

Added new - changed entries from Fix up LCD_PROGRESS_BAR

Fix homing and leveling

Added support for Atmega 1281 chip

for when no LCD is defined.
Fix for #1770.

Updated documentation in Configuration.h.
Cleaned up and commented some code relating to Z_PROBE_ENDSTOP.
Separated Z_MIN_ENDSTOP and Z_PROBE_ENDSTOP completely.

Fix: Audio feedback for MENU_MILTIPLIER_ITEM click

Added new trasnslatable labels.

- Include the current Z when raising the axis after and between probing
- Add `sync_plan_position_delta` for parity with `sync_plan_position`
- Clean up and clarify `M48`, `dock_sled`, and others

and use them in temperuture.h

Flattened the if structure - the preprocessor is doing the work - not the Arduino. Arduino.

replaced GE0 with th matching GEX in the second row.
