IncRedis is now held by Response, if requested by the base class. Response objects know their names, and they use it to load the html (soon to be mustache) data from disk. Main only prepares a factory, the factory then instantiates the actual Response. The code now correctly serves index.cgi when the request is /. Remove kakoune's safe_ptr from inside src and put an updated one in lib/kakoune.
