10.0.1 chemspill

Instead of the 10.0.1pre test release I was planning to make, Mozilla has identified a high-priority security and stability issue in 10 that we are affected by, so we now have a 10.0.1 available. All users are advised to upgrade. I also snuck in a fix for issue 129, since it was a low-risk repair. The faster JavaScript engine Ben was working on will be in 10.0.2pre once I have finished merging the G3/G4 and G5 versions together; they are different code paths in this version. We will talk more about that when it is available.
