Use _temp_error() for all errors thrown by different mechanisms

Now ending in an endless loop.
Tidy up the output format.
We now get:
ERRORTEXT ", system stopped! Heater_ID: " HEATERID

Where ERRORTEXT can be:
"Heating failed"
"Thermal Runaway"
"MAXTEMP triggered"
"MINTEMP triggered"
and soon
"Thermal Jump"

HEATERID can be
0, 1, 2 ,3 , "bed"

This messages are always followed by the common:
"Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)"
