Allow Edit menu to call fn after edit; Fix PID Ki and Kd display in menus; Actually use changed PID and Max Accel values
Add new 'callback' edit-menu types that call a function after the edit is done. Use this to display and edit Ki and Kd correctly (removing the scaling first and reapplying it after). Also use it to reset maximum stepwise acceleration rates, after updating mm/s^2 rates via menus. (Previously, changes did nothing to affect planner unless saved back to EEPROM, and the machine reset).
Add calls to updatePID() so that PID loop uses updated values whether set by gcode (it already did this), or by restoring defaults, or loading from EEPROM (it didn't do those last two). Similarly, update the maximum step/s^2 accel rates when the mm/s^2 values are changed - whether by menu edits, restore defaults, or EEPROM read.
Refactor the acceleration rate update logic, and the PID scaling logic, into new functions that can be called from wherever, including the callbacks.
Add menu items to allow the z jerk and e jerk to be viewed/edited in the Control->Motion menu, as per xy jerk.

* Not supported by non - linear delta printer bed leveling .
* Example : " G29 P4 "
*
* S Set the XY travel speed between probe points ( in mm / min )
*

*
* V Set the verbose level ( 0 - 4 ) . Example : " G29 V3 "
*
* T Generate a Bed Topology Report . Example : " G29 P5 T " for a detailed report .
* This is useful for manual bed leveling and finding flaws in the bed ( to

* Not supported by non - linear delta printer bed leveling .
*
* F Set the Front limit of the probing grid
* B Set the Back limit of the probing grid
* L Set the Left limit of the probing grid
* R Set the Right limit of the probing grid
*
* Global Parameters :
*
* E / e By default G29 will engage the Z probe , test the bed , then disengage .
* Include " E " to engage / disengage the Z probe for each sample .
* There ' s no extra effect if you have a fixed Z probe .

* r_T = [ cos ( phi ) - sin ( phi ) ;
* sin ( phi ) cos ( phi ] * r ;
*
* For arc generation , the center of the circle is the axis of rotation and the radius vector is
* defined from the circle center to the initial position . Each line segment is formed by successive
* vector rotations . This requires only two cos ( ) and sin ( ) computations to form the rotation
* matrix for the duration of the entire arc . Error may accumulate from numerical round - off , since
* all double numbers are single precision on the Arduino . ( True double precision will not have
* round off issues for CNC applications . ) Single precision error can accumulate to be greater than
* tool precision in some cases . Therefore , arc path correction is implemented .
*
* Small angle approximation may be used to reduce computation overhead further . This approximation
* holds for everything , but very small circles and large MM_PER_ARC_SEGMENT values . In other words ,
* theta_per_segment would need to be greater than 0.1 rad and N_ARC_CORRECTION would need to be large
* to cause an appreciable drift error . N_ARC_CORRECTION ~ = 25 is more than small enough to correct for
* numerical drift error . N_ARC_CORRECTION may be on the order a hundred ( s ) before error becomes an
* issue for CNC machines with the single precision Arduino calculations .
*
* This approximation also allows plan_arc to immediately insert a line segment into the planner
* without the initial overhead of computing cos ( ) or sin ( ) . By the time the arc needs to be applied
* a correction , the planner should have caught up to the lag caused by the initial plan_arc overhead .
* This is important when there are successive arc motions .
