Tired of trying to debug things like classpaths...

Tired of trying to debug things like classpaths only to see output like
the following:

/System/classes/you/already/know:/Importan...]

I added a "do not truncate" mechanism to reporter and put it to use. Now
scala -verbose will let you in on those classpath secrets. No review.
