Add an emergency-command parser to MarlinSerial (supporting M108)
Add an emergency-command parser to MarlinSerial's RX interrupt.
The parser tries to find and execute M108,M112,M410 before the commands disappear in the RX-buffer.
To avoid false positives for M117, comments and commands followed by filenames (M23, M28, M30, M32, M33) are filtered.
This enables Marlin to receive and react on the Emergency command at all times - regardless of whether the buffers are full or not. It remains to convince hosts to send the commands. To inform the hosts about the new feature a new entry in the M115-report was made. "`EMERGENCY_CODES:M112,M108,M410;`".
The parser is fast. It only ever needs two switch decisions and one assignment of the new state for every character.
One problem remains. If the host has sent an incomplete line before sending an emergency command the emergency command could be omitted when the parser is in `state_IGNORE`.
In that case the host should send "\ncommand\n"
Also introduces M108 to break the waiting for the heaters in M109, M190 and M303.
Rename `cancel_heatup` to `wait_for_heatup` to better see the purpose.

Add the socalled "Babystepping" feature.
It is a realtime control over the head position via the LCD menu system that works _while_ printing.
Using it, one can e.g. tune the z-position in realtime, while printing the first layer.
Also, lost steps can be manually added/removed, but thats not the prime feature.
Stuff is placed into the Tune->Babystep *
It is not possible to have realtime control via gcode sending due to the buffering, so I did not include a gcode yet. However, it could be added, but it movements will not be realtime then.
Historically, a very similar thing was implemented for the "Kaamermaker" project, while Joris was babysitting his offspring, hence the name.
say goodby to fuddling around with the z-axis.
