Things should be pretty stable for a while.   
But it wouldn't surprise me if the Delta people have a need for a few special commands.

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

This is what I did yesterday:

- basicly gave the tests more comprehensive names; put all the
declarations at the top; got rid of the magic negative C-value (renamed
to P + A, O, T)

- "cos(RADIANS(180 + 30 * axis)) * (1 + circles * 0.1 * ((zig_zag) ? 1 :
-1)) * delta_calibration_radius" compiles wrong is zig_zag statement is
without brackets

- DELTA_TOWER_ANGLE_TRIM reset to 3 values (the calcs use the 3th value
to normalize will not compile otherwise)

-Wrote 3 dummies to keep EEPROM lenght the same

-Reset the configs to the 'original' with autocal + menu disabled (but
can be enabled of course)

As proffered in #6252

M666

+ tower radians absolute value

Giving a negative number of probe points disables the tower angle
correction calibration ('4point' instead of '7point' solution)

EEPROM version updated

Fixes #6393

- Making M665 compatible with repetier (see
http://reprap.org/wiki/G_code#M665:_Set_delta_configuration)

- M665 B also sets the radius for manual calibration menu

- Converting tower ajustment definitions to arrays - tower angle
corrections compatible with Esher 3D wizzard

- Only tower angles need to be adjustable with M665 and stored to EEPROM
- tower radius and diag rod can be adjusted in the FW only with #define

Configuration_store.cpp - changed a couple of print statements so the
values were printed.  The old method resulted in the formula being
printed.

ubl_G29
1) added support for R option to P4.  Now probes all points unless R is
present and the number is greater than 0.

2) P2 - moved map print statement so it showed the point that was
currently being probed,  The old location did this only for the first
point.

3) P4 - Moved the map print for the same reason.

ultralcd.cpp - changed "Mesh Editor :" to "Mesh Editor" because the LCD
draw routine puts a ":" in automatically so you end up with an extra ":"
using the old message.

- On `DELTA` the `M665 H` option supplants `M206`
- On `DELTA` `NO_WORKSPACE_OFFSETS` only reverts `G92` behavior
- Spawn 4 conditionals based on `NO_WORKSPACE_OFFSETS`
- Optimize coordinate space conversion for `DELTA` workspace
- To keep EEPROM version, retain `home_offset[XYZ]`, just ignore XY

Resolve 'steps_to_mm was not declared in this scope' compilation error after recent changes to merge babystepping with M851

I use the movement options via LCD quite often. Especially to get the nozzle out of the way. I see no reason, why the 10mm option is disabled for the Z-Axis, this is why i always delete this line when i compile a new version.
If this is unwanted, please just close this PR

When PARK_HEAD_ON_PAUSE is defined Marlin won't compile because of two missing semicolon.

# This is the 1st commit message:

MCP4728 consistency & fix ultralcd.cpp

The MCP4728 DAC controls the stepper motor current strenth on the
PRINTRBOARD Rev F and RIGIDBOARD V2 boards.

PR #5792 on 9 FEB 2017 implemented default drive percentages but only on
the RIGIDBOARD V2.

This change moves the default settings to Configuration_adv.h.

Also, ultralcd.cpp won't compile because of a type def conflict.
Changed it to match the one in stepper_dac.cpp

===========================================================

reword stepper curent section for clarity
