Font adjustment to improve viewing in Windows (the default monospaced font,
    Courier New, seems to have no reasonable size in IE!)
Improve error handling.  Try very hard to distinguish between failure to
    find a module and failure during the module importing process.
Improve reloading behaviour.  (Still needs some work.)
Add '.' to sys.path when running as a script at the command-line.
Don't automatically assume '-g' based on the platform.  We'll just have
    the batch file supply -g.
