Title: display warnings by default or when debugging

Issue #229 (a39a868) attempted to fix Excon's warnings to respect Ruby's verbosity conventions.
However, those changes disabled warnings by default.
The [referenced article](http://mislav.uniqpath.com/2011/06/ruby-verbose-mode) refers to the global `$VERBOSE`, not `ENV['VERBOSE']`.
