  NETCURL-287:
  * Primary commit for NETCURL-287. * Created a GenericParser class for generic parsing of data, when many wrappers use same functions. * WrapperConfig uses same stream-storage for streams that it does for the soapclient. * WrapperConfig now support XML encoding via IO-Content (NETCURL-288). * setStreamContext sets both http and https data for some wrappers (setDualStreamHttp). * WrapperConfig now supports normal non-soap-basic auth. * As curl is the first option with a fallback to streams (file_get_contents) wrapper is no longer throwing on absence. * Changed error message for instantion exceptions (and fixed typo). * Tiny cleanup.
