[PATCH] Improve run-time overloading documentation

The overload.pm documentation suggests eval "use overload ..." to 
achieve run-time overloading. The heavy hammer of string eval for this 
purpose is kind of silly. Instead I suggest the deconstruction of the 
"use" and "no" into require then overload->import or overload->unimport 
directly, much like we describe in perlpragma.

The second patch adds me to AUTHORS. :)

and: http://grep.cpan.me/?q=eval%5Cs*%22%28use%7Cno%29%5Cs%2Boverload

Thanks,
Shawn
