Thermister -> Thermistor

Added support for BQ ZUM Mega 3D board and stock Hephestos 2 thermistor.

//100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed)

Caveat Emptor —- 
I’m not sure that this really makes sense,
but why keep someone from using it?

Keep "astyled" reformatting

Added a second sensor and made them configurable.

Am I the only one who always need to change the thermistortable.h to add
a dummy table??
Ok, it is done. Just set the thermistor to 999 and it will always read
25C. Great for Testing or Development purposes.

Wrong number on line 627 > i change number "12" by the correct number "13"
Soory

Add another thermistor table (13),it's a cartridge thermistor up to +300°C,use with Hotend "Simple ONE" & "All In ONE"

Generated with createTemperatureLookup.py. The old table crapped out at
270C, which was a problem for polycarbonate.
