Fix: Build error when EEPROM_SETTINGS is defined and PIDTEMP is undefined

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.

Separate PID_MAX from BANG_MAX

HTML removed, Rumba added

The LARGE_FLASH flag allows superfluous features to be excluded
on boards with less memory

The new version of the library means that PANELOLU no longer needs to be
defined in LiquidTWI.h (the library file can be used as is) and the new
version of the library also enables the buzzer on the Panucatt VIKI
panel.

This allows PID_FUNCTIONAL_RANGE to use a maximum duty cycle higher
than PID_MAX. This is useful for powerful heaters to heat quickly in
bang-bang mode, but use a lower duty cycle that is easier to stabilize
in PID mode.

Found some unwanted html at the bottom of the file which caused it to not be able to compile.
Also added rumba as machine.

This code selects between the routines for the GLCD or the char.

A new variable was introduced to allow fan animation on the GLCD.
Add additional float to string conversion routine without sign
character. This is used for the coordinates visualisation on the GLCD.

This contains the menues, status screen etc...

Sorry for that. This does not lead to compile errors. I removed the

Fix step rate bug (especially for retraction)

These definition contain also the definition for the graphics LCD.

Definition for the graphic LCD are already in it, they will not harm the
configuration as they are only defined constants

Add STB board support to Marlin (next step towards graphic LCD implementation)
