Move web module from cubicweb to the new cube cubicweb_web
Just move module and do not change anything.
Add import * from cubicweb_web.
into CubicWeb web module files.
The web module tests stay in CubicWeb (for now)
The configuration from web module, go to the cubicweb_web cube. It will be adapted later.
Move cubicweb/view.py
to the cubicweb_web cube with the import *
in CubicWeb.
