Added the possibility to set the "Status" header (different from the status line) in GW_HEADER

Browse Source 
Renamed EWSGI_RESPONSE as EWSGI_RESPONSE_STREAM to avoid confusion with EWSGI_RESPONSE as stated in Paul's proposal
Added default "configuration" (for nino and cgi) to be independant of the connector (at compilation time)
Added example implementing Paul's proposal on top of EWSGI
