Core software 0.9.13 released

[Dave Ackley]

sfb-latest.zip and sfb-latest-html-docs.zip
have been updated to version 0.9.13. At
http://livingcomputation.com/ixm/pub.

Some brief change notes at
http://robust.cs.unm.edu/doku.php?id=news

Two significant changes, one mostly
internal and one sketch-visible. First,
boot3.hex, the tertiary bootloader, is
built in Thumb mode to save space, and
it is not built by the default 'make'
command.

Second, a fast profiling system has been
added, allowing you to determine where
all the microseconds are actually going.
Have you ever suspected that interrupts,
or perhaps alarm handlers, were eating
up all your time? Now you -- or your
sketch -- can know!
