snuck in twitter card style for crowcpp.org site (makes social media cards look way better with a large image)

Added std::string() operator to json::rvalue (allows std::string(json["abc"]), which returns any value that isn't a container to string)
Added lo() method to json::rvalue, returns a vector of json::rvalue containing whatever a json object or list has (difference being a list has no keys)

Made json::wvalue use either std::map or std::unordered_map instead of just std::unordered_map
Added copy constructor to json::wvalue
Added size() method to json::wvalue, returns 1 or the size of the json list.
Added constructor to create json::wvalue from std::vector

The reason is the missing keyword PRIVATE/INTERFACE/PUBLIC in the offending line.
This edit fixes this.
Does anybody know whether the big red "Delete File" option when reviewing commit deletes the entire file from the repo or just from the commits (or the PR)?
