* Enable compiling vweb with -prod (by supressing 'declared and not used' warning about 'reset') . * Fix http responses (now wrk is happy and shows no errors) by adding a Content-Length header. * Fix -g compilation for urllib.v . * vweb: println action= only in debug mode. * vweb: max request headers counting fix. * Make vweb.html get a 'ctx mut Context' param, just like the other methods. * vweb: simplify add_header. * Use a string builder for the most common html case so that the response http text can be send in one go. * vweb: reduce _STR/string interpolation usage in the most common html response case. * vweb: refactor common http response formatting into Context.send_response_to_client/2 method.
