There’s no need to ask users to uncomment Max Endstop pins when they

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

Replace instances of the number 13 with FILENAME_LENGTH where
appropriate.

Githun insert this line when i merge with actual Branch development...

Done

This define is not used.

Without this fix, the code wont compile with extruder but without bed
runaway protection defined.

removed function step_wait() from stepper.cpp because its used nowhere.
