Implement bound methods

[GoogleCodeExporter]

A reference to a method should be equivalent to a closure with the same calling 
signature. This may require generating a calling adaptor in the compiler. For 
example:

class Foo {
  def bar() {
    Console.out.writeLn("Hello!");
  }
}

let obj = Foo();
let func = obj.bar;
func(); // Should print "Hello!"
