The character 0x7E is common in 8.3 filenames. Maybe the last condition
should be removed completely instead.

Introduce temp watch protection for the bed

Pins cleanups

Encapsulate Stepper, Planner, Endstops in singleton classes

When setting the bed temp via M140/M190 if the thermistor does not read an increase of WATCH_BED_TEMP_INCREASE degrees by WATCH_BED_TEMP_PERIOD seconds then it will throw "Error:Heating failed, system stopped! Heater_ID: bed" and call the kill() function.

Don't reject 8.3-filenames with chars > 0x7f

Prevent stuck M109/M190 when target is changed

Don't mangel 8.3-filenames with chars > 0x7f

Windows produces 8.3filenames wit chars > 0x7f. Those have been rejected
by Marlin until now.

With these 'malformed' filenames can now be worked with:
In the LCD menue
With RepetierHost (V1.6.1 tested) - full support. Characters are
displayed as '?'
With Octoprint (1.2.10 tested) the files do not appear in the files
area. At the console, listed with M20 they appear with a '�'.
With Pronterface the files appear in the sd-window but you can't start
them. They are mangled by pronterface. The names are altered and than
recected by Marlin. In the console they apper with differen but not the
correct characters.

All in all a little step forward.
