Did some more modifications...

* Using "avoid_unused_variable_earning" name.

* Moved header to boost/utility/warnings.hpp -- No use in poluting the
boost/ include path when there's a perfectly good subdir for the file.

* Added start of documeting the various messages that compilers give for
this warning as suggested by Paul.

New archive at:

http://groups.yahoo.com/group/boost/files/warnings.zip

And attached.

TODO's:

* Add section on cost, Paul suggested runtime cost, but it's worth
mentioning the compile and link costs also. Need to investigate what those
are first.

* Add more known compiler warning messages.

Enjoy, and thanks for the feedback, past and future :-)
