QWeb views allowed to render QWeb templates rendered by the server in
a view.
Today, QWeb views are only used in website to see the hierarchy of
their views. The use case of website has now more sense in a client
action rather than an extension of a QWeb view.
This commit removes this view because it is not used anymore and will
probably not find any useful use case in the future.
