Allow BL-Touch users to control heaters during probe event (#6485)
The Configuration.h file entries for BL-Touch have been updated to:
```cpp
//#define BLTOUCH
//#define BLTOUCH_DELAY 375 // (ms) Enable and increase if needed
//#define BLTOUCH_HEATERS_OFF // if defined the printer's heaters are
turned off during probe event
```
Add my two 'Nice' machines as example configurations
These are my two 'Nice' machines. Both are good example machines. The
FolgerTech i3-2020 is probably the best value kit on the market right
now. And it has developed a 'Cult Following' of hobbiests. I'll always
have an up to date Configuration.h file set for it, so it may as well be
an example configuration.
And the gCreate gMax 1.5+ is the best printer I've ever seen that runs
Marlin. For sure, I'll always have up to the minute Configuration.h
files for this printer also. I've moved over to using the gMax as my
primary development machine for Marlin. So... Besides being a good
machine, it is a nice convienience for me to have this Configuration.h
file as an 'Example'.
