Added temperature status less.

Hopefully fixed viky button handling without braking other boards

Marlin/Configuration.h

 // Increase the FAN pwm frequency. Removes the PWM noise but increases heating in the FET/Arduino
 //#define FAST_PWM_FAN
 
+// Temperature status leds that display the hotend and bet temperature.
+// If alle hotends and bed temperature and temperature setpoint are < 54C then the BLUE led is on.
+// Otherwise the RED led is on. There is 1C hysteresis.
+//#define TEMP_STAT_LEDS
+
 // Use software PWM to drive the fan, as for the heaters. This uses a very low frequency
 // which is not ass annoying as with the hardware PWM. On the other hand, if this frequency
 // is too low, you should also increment SOFT_PWM_SCALE.
