Add minify option, which eliminates most whitespace (but not as good as uglify). Add --watch to gorilla command, needs more work. Make async! throw work to automatically throw instead of passing to a function. Add support for generic functions (not just classes).

Add jsutils, which handles some JS-related functions, use to-JS-source instead of JSON.stringify in the browser output
Make type serialization a bit more terse for common types (which exist on the Type class).
Make the prelude serialization for helpers remove any unnecessary dependencies.
Make some of the prelude serialization a bit terser.
