DSL for handle binding

[Charles Oliver Nutter]

I have pushed what I have so far to http://github.com/headius/invokebinder

There are tests for everything except "cast" so far, but I have not
added all handle transforms. I'd love to have contributions, and will
happily add anyone that wants to contribute :)

Note: I could not figure out how to get Maven to pass the appropriate
invokedynamic -XX parameters to the JVM. If someone knows how to do
that, please show me.
