WINDUP-246: Add a Windup Report with all non-classified/non-hinted files...

https://issues.jboss.org/browse/WINDUP-246
There is no obvious thing to extend, and no obvious place to put this (since it ends up covering multiple types, and depends on high level reporting models).

Inlining it would work, but would also have the side effect of making it harder to unit test.

I'm open to suggestions, though... have any ideas of a better place to put it?
