make CGI::Application::Plugin::DevHelp an OPTION
Currently, p5-CGI-Application-Plugin-DevHelp is a hard dependency in p5-CGI-Application-Plugin-TT. However, C::A::P::TT operates just fine without it. The attached patch turns the dependency into an OPTION that defaults to on.
Just for the sake of having a reference, http://cpansearch.perl.org/src/CEESHEK/CGI-Application-Plugin-TT-1.05/META.yml lists it as a "recommends" but not a "requires."
