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.

The welcome message is more appropriate than “resuming print” if
nothing is printing.

Allow M0 and M1 to include a message string. Ignore clicks on “Wait for
user” so that the Info Screen stays up.

Add Travis CI config to build Marlin firmware.

Changed graphic LCD info screen to match the set # of extruders

Here comes a compile-time operation to match the extruder symbols on the
info screen to the set number of extruders in configuration.h.
When only one extruder is selected, the "1" on the symbol will not be
displayed.

Added some background on the filament sensor to explain it better.

Added support to show the filament width on the status line of the
graphic LCD.  The status will show for 5 sec and then switch over to
data.  Status can be seen by clicking the button.

Changes to support displaying the real-time filament width and the
volume factor on a 20x4 LCD.  The data is displayed on the 4th line.
First the status message is displayed for 5 seconds, and then the
filament data is displayed.  The status message can be seen by
re-selecting the info screen in the menu.

Comment out the FILAMENT_SENSOR define by default in config.

Commented out the FILAMENT_SENSOR define so that it is not enabled by
default.  Code does not work on all hardware variants.
