Tosh stepper drivers need to be driven slower, so the stepper code
was interleaved to separate the pin HIGH from the pin LOW. This adds
enough instructions to make it work, without needing nops.

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.
# The first commit's message is:
SD Card Alpha Sorting
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.
# This is the 2nd commit message:
Expand on More RAM concept, address minor bugs
# This is the 3rd commit message:
Improvements, more SORT_USES_MORE_RAM
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.
# This is the 4th commit message:
Completed SORT_USES_MORE_RAM implementation
