Update ConfigurationStore to always write dummy values for disabled
options, including FWRETRACT, DELTA, and SCARA. Update the EEPROM
version to “V15.” Also fixes a buffer overrun with axis_scaling in
Config_ResetDefault.

This won’t reduce the string storage in the end, but it makes the
language files smaller. Also removed remaining unused strings.

Also fix analogInputToDigitalPin so it uses proper C hex notation

There’s no need to ask users to uncomment Max Endstop pins when they
have them. These will be set to -1 later if the endstop option is
disabled.

#1405 includes some changes to pins.h for a 4th extruder. This commit
applies those changes. It also deals with a possible problem with
SENSITIVE_PINS.

Hopefully this is helpful to organization and future expansion….

Moved #endif to allow filament settings to print.

Added PIDTEMP dummy write to align EEPROM read/write operation.
