heater code. Also remove the temp_achieved() declaration
in heater.h, which has no definition in heater.c.
If you wonder about what might be the use of not having a heater,
think about a paste dispenser or an externally heated extruder :-)
Having no heater removes a whopping 1200 bytes of program size.
can't think of a situation where resetting the controller in the middle
of a build would be useful. Even hanging ist better :-/
The difference in program size is just 238 bytes.
