G0 to G3 were previously acknowledged in the get_command method, causing
them to be possibly acknowledged before commands coming after them that
were acknowledged in process_commands.

This patch fixes this, moving the acknowledgement of G0 to G3 to the
process_commands method as well. These commands are therefore no
longer acknowledged when the enter the cmd_buffer but instead only
acknowledged when the enter the plan_buffer.

Guaranteeing that commands are acknowledged in the same order in which
they were received by the firmware allows host software to be able to
track the life cycle of commands and such a better management of the
firmware's serial buffers as well as better internal command processing
and response parsing without having to depend on throwing an epic
amount of regular expressions against each line received back from the
firmware.

Fixes ErikZalm/Marlin#1147

Added boards.h which contains defines for all the board numbers, plus
some shorthand macros for less typing.

Breaking up languages.h makes it easier to translate. Using language
codes makes it easier to select a language and sets the naming standard.

For legacy boards it’s better if this option is disabled.

For the MORE_RAM option we need to buffer both the short and long
names, even though long names are sometimes redundant. Worst case, all
the names are max length. We can save some RAM by not storing these. We
could save more RAM by only storing the visible part of the long name.

With this option, always keeps the dir in RAM, doubling as a cache for
getfilename. A board with only 8K of SRAM is cutting it very close.

First iteration of alphabetical sorting for SD cards, both
slow+efficient and fast+rammy. Option for folders to sort first, last,
or not at all.

Messages in gcode files like “M117 Printing…” were not being cleared on
Stop Print.
