Parentheses need here otherwise sanitycheck.h does wrong thing on line 222

Give all temp arrays 4 indices

- Also patch up some warnings

- Fix a bug reading `code_value` for `M503 Sn`
- Hide and remove unused variables

Latest upstream commits

Always 4 temp sensors

- Also a small tweak to SanityCheck.h

Avoid warnings in SanitiCheck.h

First aid for #1703

- Increase the probe offset range to -20…20
- Apply the range limits to the menu item

/SanityCheck.h:107:53: warning: missing terminating ' character
...

to avoid:
Marlin_main.cpp:1790: warning: array subscript is above array bounds.

Clean "fromsd" array if not SDSUPPORT

- Put + in front of positive values in the output

Instructions for Mesh Bed Leveling

Latest upstream commits

Move definition of PIDdT back to temperature.h

Don’t set CUSTOM_M_CODE_SET_Z_PROBE_OFFSET if there’s no Z probe

- Make `zprobe_zoffset` conditional
- Fix ConfigurationStore for `zprobe_zoffset`

- Init `zprobe_zoffset`
- Remove `current_position[Z_AXIS] = zprobe_zoffset` lines from the
`set_bed_level_equation_*` functions
- Apply standards to `mesh_bed_leveling` files
- Document `MESH_BED_LEVELING`

Fix MAX6675 again and introduce set_current_temp_raw()

if not have SDSUPPORT the fromsd array is not necessary

It just probe all the bed without appliying the matrix.
Useful after a first G29 to check the topology.

make it unconditional
remove all definitions in the 'Configuration.h's
remove form 'Conditionals.h'

to make the temperature-code work again with Arduino 1.0.6.

Sorry could not make an extra block on base level.

Add the missed {} to END_MENU in ultralcd.cpp

what caused an extra update of encoderLine most of the time.

ZigZag: Inverted Behavior.. If T supplied, it does not zigzag.
Topograph table: The table was rotated 90º clockwise.

Z_DUAL_ENDSTOPS is a feature to enable the use of 2 endstops for both Z
steppers - Let's call them Z stepper and Z2 stepper.
That way the machine is capable to align the bed during home, since both
Z steppers are homed.
There is also an implementation of M666 (software endstops adjustment)
to this feature.
After Z homing, this adjustment is applied to just one of the steppers
in order to align the bed.
One just need to home the Z axis and measure the distance difference
between both Z axis and apply the math: Z adjust = Z - Z2.
If the Z stepper axis is closer to the bed, the measure Z > Z2 (yes, it
is.. think about it) and the Z adjust would be positive.
Play a little bit with small adjustments (0.5mm) and check the
behaviour.
The M119 (endstops report) will start reporting the Z2 Endstop as well.
