To deal potential z scaling when fade is enabled, a fade_target option has been introduced. This option may either be set to 0.0 or any z position within the range of the mesh. A value of 0.0 will result in previous behavior, where z adjustment phases out until no further adjustment is added. A non-zero value will phase out adjustment until the target has been reached, after which the rest of the print will be offset along the z axis by the fade_target. By default the fade_target will be calculated as an average of the mesh.

Cheap mechanical servos have small flickering. When this servo stay on one position, this flickering slowly destroy internal potentiometer and make servo unusable. Many mechanisms need servo only to change position. Therefore I create this minor path to enable/disable servo. It stop pulses for this servo, that's all.
Corresponding G-code is:
SET_SERVO SERVO=config_name [WIDTH=] [ENABLE=<0|1>]
SET_SERVO SERVO=config_name [ANGLE=] [ENABLE=<0|1>]
For example:
SET_SERVO SERVO=touch ANGLE=80 ENABLE=1 ; enable servo and set position
G4 P200 ; wait 200ms
SET_SERVO SERVO=touch ENABLE=0 ; disable servo
This patch add one option to servo configuration:
enable: <False/True> # default True
It not have impact to user code existing already because it is optional parameter and default value is same as original behavior.
