Fixes the make_doc.sh, <, > and & signs in descriptions that cause the parser to break.

Documentation for HTTPClient.
Added a query_string_from_dict method to HTTPClient to create a x-www-form-urlencoded valid query string for GET and POST messages.
String now has http_escape() and http_unescape() methods to help facilitate the above query_string_from_dict method.
