Windows Installer

Our current Windows installer works, but ideally, we would integrate parts of the PellesC distribution into the installer so that someone can have a working OpenDylan installation out of the box without having to worry about linkers and C compilers.

This involves:

• Determining the subset of PellesC that is needed.
• Installing that into an appropriate place within the Open Dylan directories.
• Modifying the build scripts to be able to find the PellesC stuff without having have the user manually set up any environment variables.

This may require a minor extension to our Jam implementation to allow setting an environment variable from within a build script.
