Beta v4.0d Released

And another beta comes out. Only one change, but a pretty useful one.

• Perform basic parsing on regular expressions in scripts. This should prevent the parser from accidentally consuming brackets, and as a consequence, taking a very long time to parse some script. 

And when I say very long, I'm talking in terms of the heat-death of the universe.

Obviously, other bugs exist which prevent me from upgrading this to a final release. But this is one of the bigger ones, and warrants it's own release.
