Implemented WSF_RESPONSE.put_error (...) and related

Added WSF_RESPONSE.put_character
Renamed  WGI_OUTPUT_STREAM.put_character_8 as put_character  to follow style of put_string  (and not put_string_8)
Refactored the WSF_DEFAULT_SERVICE_LAUNCHER
Added WSF_DEFAULT_SERVICE to be more user friendly
Splitted the wsf/default/ libraries to have wsf/connector/... and being able to handle more than one connector in the same application
