- update comment section
- redefined P5 grid
- minor clean to probe radius routine
- updated EEPROM version to V37 according remark in #6517

* Fix Horizontal and Vertical optimization bug.

And drastically reduce the debug code foot print....

* Yeah Baby!

The debug print is going A - OK !

- Only call `set_heaters_for_bltouch` when actually deploying/stowing
- Clear `next_emi_protection` when re-enabling heaters

add BLTouch-related messages in english and (rusty) french;
add missing endstops.h in ultralcd.cpp;
fix misc. compiler warnings;
fix lsf_reset - ZERO macro can't handle a pointer as it would only memset the size of the pointer, not the size of the entire struct

Motor current defaults need to be defined for Rigidboard

Right now G26 doesn't send a notice to the host that it's running.  It's
not until the heaters are at temperature that you know for sure if it's
running or not.

Added host temperature prints so that someone watching the host
interface will see the temperatures change during the warm up period.
Updates are sent every 5 seconds.

Also added the new .pio-related directory to .gitignore, and a few ignores for those who use cmake.
