use the getBool method (and formatting cleanup)
getCurrent* should always look up the parent chain, because we could be inside a block or something like that and we need to not restrict ourselves to just the local env
parent is no longer accepted as a constructor parameter
provide access to the environment
make sure to run the bootstrap when testing the parser
fix the usage of getCurrentPackage
some formatting tweaks
fix getBool so that it never creates
we don't throw these exceptions anymore
fixing the toString methods a bit
