* Initial conflict resolution
All previous items resolved:
- Use of ELAPSED() on timer code
- Switch to use of defer_return_to_status=true as much as possible
- Update & Clean Up of Max7219 routines
* Resolve non-SD case in ultralcd.cpp
Ideally, it should be calculated based on Z steps per unit so that each
babystep corresponds to around 0.025mm. Smaller than this is largely
insignificant for typical layer heights.
* Add MAX7219_DEBUG to Travis CI testing
* Tweak config and use standard pin naming for MAX7219_DEBUG
* MAX7219: Apply coding standards, use macros, etc.
* Make code work...
* [New Feature] I2C position encoder support
I plan to continue improving/cleaning this up, as there areas that need work.
* let the cleanups begin.
* progress
* more progress

* misc.
* Fix up I2CPEM.init() and a few other things.
* organize, fix, rename, etc.
