Markus Hitter 77630167e7 Serial: postpone sending "ok" until a slot is free. 
Previously acknoledgement was sent as soon as the command was
parsed. Accordingly, the host would send the next command and
this command would wait in the RX buffer without being parsed.

This worked reasonably, unless an incoming line of G-code was
longer than the RX buffer, in which case the line end was dropped
and parsing of the line never completed. With a 64 bytes buffer
on AVR this was rarely the case, with the 16 bytes hardware buffer
on ARM LPC1114 it happens regularly. And there's no recovering
from such a situation.

This should solve issue #52.
