-- fully qualified methods
-- Java 8 lambda expressions
-- new SwingJS-site.zip runtime Clazz

Note that functional interface methods (methods in singleton Interfaces)
are still aliased both in their fully parameterized forms and their
unparameterized forms. This works for proxy, but it is not ideal.
Ideally, we would be giving the minimum signature for the interface
method parameters. I just don't have a way of doing that.

refactored class creation and invocation handling

- lambda functions
- doublecolon operator
- java.util.function
- java.util.stream

- all methods post-$ qualified except Math.* and *.toString()

Unqualified names reduced to Math::* and *.toString

Plugin structure simplified. Just four files:

Plugin.xml
CompilationParticipant.java
Java2ScriptCompiler.java
Java2ScriptVisitor.java

Unqualified names reduced to Math::* and *.toString
