Note that this way, it is easy to redefine `launch' in order to customize the launching instruction if needed (thinking about testing...)
This might breaks some code since it adds a `launch' feature, but it is easy to fix and unlikely to happen often.
Added WSF_DEFAULT_RESPONSE_SERVICE
Added simple WSF_SERVICE_LAUNCHER_OPTIONS_FROM_INI class to load launch option from ini file.
Removed a few obsolete features
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
