There's no changelog for this build other than notes in individual
scripts. I'd summarize it by saying this one works slightly better than
the previous build. Mostly there's internal code cleanup, things work a
bit faster than before, etc.

There's still a known issue where if you switch between the chalkboard and
alabaster motifs the colors don't propagate correctly immediately until
the next time you close and relaunch the editor. I won't be able to look
at that until after the conference. Ideally I will see issues posted on
bitbucket, we'll have to try it.

And I've occasionally run into that thing where there's no error info
before. Not consistently enough to have anything to fix, though. And
sometimes compiling a second time does highlight the error. I'd love to
have a recipe that just failed the same way every time. It's probably on
my plate to fix that because it has to do with interaction between the
script editor and the debugger.
