- The status screen uses the ST7920 character generator to greatly
reduce SPI traffic and MCU load when updating the status screen.
- Has been tested with the RepRapDiscount Full Graphics Smart Controller
but should work with any LCD that uses an ST7920 or fully compatible
controller.

Updating I2C position encoders to enable babystepping and Babystep XY when using the ecm microstep correction method. Also changed default method to ECM microstep.
* Work around for serial buffer over run
PronterFace sends a lot of M105 commands. During long operations such
as UBL's G29 P1, G29 P2, G29 P4 and G26 this can over run the serial
buffer. This results (very often) in a M1 (actually a M1M105) ending
up in the command queue.
Until we figure out a better way to resolve this issue, this will keep
the UBL commands from experiencing bogus commands at thier completion.
A number of regressions were patched also. The UBL G29 P2 and P4 Press and Hold had stopped working. It is very possible this is broken in the bugfix_v1.1.x branch also.
The main purpose of the Pull Request is to get the 3-Point mesh tilting to use the LSF algorithm just like the grid based mesh tilt. This simplifies the logic and reduces the code size some what. But the real reason to do it is the 3-Point case can be solved exactly. And by feeding these numbers into the LSF algorithm it provides a way to check all that code for 'correctness'.
