mclint.refactoring now mclint.patterns.rewrite

The little transformations based on the unparsed patterns stuff
can't really be called refactorings.
Remove unused variables (proof of concept)
Run until fixed point, and discard obsolete messages
Naive implementation of rename variable
Make NodeFinder return a lazy iterable.

This removes the need for the transform and filter methods, since
now Iterables.filter and Iterables.transform work just as well
without an extra pass. Since this was really the only value added
by the fancy new API, I've reverted it back to the three public
static methods (de-deprecating them), except that find returns an
Iterable instead of a List. (I've also switched the order of the
parameters to type, node instead of node, type in all three
methods). I also went and fixed all the call sites.
Have javac ant task include debug information.

This will get rid of the (Unknown Source) in stack traces.
