Example Configuration.h files are not updated yet.   You need to cross
your settings over to the default Configuration.h file in the \Marlin

location in the file.)

For parity with bugfix-2.0.x

Just aligned with version 2.0. Here bug was not present

This PR will address two issues reported in #8492. Just one is left because I don't know if it is an issue or not

1) when no home is done ("no_move" is set) tool change should never move X & Y because... I don't know where I am...only Z should be adjusted to avoid bed collision if other nozzle is lower than current.
2) Since no move no bed level matrix should be applied
    When SWITCHING_NOZZLE is enabled and system is homed there are two movements to go to destination, but first can move Z to older position and then crash on the bed

* Fix up Travis CI and compile warnings/errors

* No ULTRA_LCD with REPRAP_DISCOUNT_SMART_CONTROLLER

* No point in setting all the endstop plugs

This fixes the old implementation of M428 which was broken, did not
match the website, and made no sense.

Thanks @RowanMeara!

Thank You MagoKimbra !

* Fix G26's circle drawing...

This mostly catches the bugfix-v1.1.x branch up to bugfix-v2.0.0

I'll have to do something similar to get bugfix-v2.0.0 caught up to
bugfix-v1.1.x

* only use planner.leveling_active if appropriate
