Renamed WGI_RESPONSE_BUFFER as WGI_RESPONSE to avoid confusion
Removed EWF_HEADER and removed related caller from WGI implementation,
now this is only part of WSF library
Added wgi_version, wgi_implementation and wgi_connector to the WGI_REQUEST interface
to give more information to the user
Added back WGI_CONNECTOR to WGI specification, mainly because of `{WGI_REQUEST}.wgi_connector'
simplified WGI_CONNECTOR to contain for now only `name' and `version'
if the implementation of connector inherit from WGI_CONNECTOR (recommended)
this might gives more access to the user using a reverse assignment for specific needs
(but this usage is not recommended due to portability issue on other connector)
Removed useless connector.ecf since now EWF/WGI library provides the helper classes
Re-adapt the Spec-compliant solution (instead of Lib-compliant solution).
Thus no more 100% deferred interface.
Rename EWSGI_RESPONSE into EWSGI_RESPONSE_BUFFER
Added in extra/response-as-result/ an copy/paste from the implementation of Paul's proposal (not up to date with Paul's spec). But this is mainly for information and tests.
Removed part of the ewsgi/specification interfaces ... to be able to test EWSGI compliant library against the pure specification (experimental).
Renamed most of the GW_... into EWSGI_...
So this is really more flexible this way, and much easier to write application supporting CGI, FCGI, Nino and so on .. as demonstrated in hello_world
This is a first version, more will come later, mainly migrating from Eiffel Web Reloaded to this Eiffel Web Framework project.
