Slight size reduction by adding idle()

Redo "invalid extruder" to save 304 bytes

- Use `setTargetedHotend` in `M200`, as with other commands that use
`T` for the extruder
- Synthesize the "invalid extruder" message, obviating several long
strings

Ignore unknown commands if they start with G, M, or T

Print active extruder with M105 for MAX6675

Separate the maximum integral power for the bed from PID_INTEGRAL_DRI…

Initialize the display earlier

Replace MSG_F? with MSG_N?

Update M33 for new gcode parser

To avoid double definitions.
I prefer to read N for Number not for Nozzle.

Was omitted when T0 is a MAX6675.

My PID_INTEGRAL_DRIVE_MAX was at 96, which was insufficient for my bed
to reach its intended temperature. The head requires a low maximum power since
I run on 24 volts and it has a somewhat low thermal mass.

Fix DEGREES macro

to have it ready to display errors during (temperature)-setup.

M110 is a known command

- The command parser now displays “unknown command” in more cases.
Known commands must be added to the `switch` inside `process_commands`
to suppress the error.

Activate BED_MINTEMP error

Call kill() only once when triggered by a temperature error

And call _temp_error() directly for ERR_MAXTEMP_BED to avoid the only one time use of bed_max_temp_error().

Includes #2156.
