I've just changed AbstractTemplateView to expose 2 new bean properties;
allowSessionOverride and allowRequestOverride both with default : false.

Current behaviour is maintained - ServletException thrown if a request or
session attribute would hide a model attribute - unless one of these prop=
s is
explicitly set to allow it.  I think this is the clearest way.

It's the simplest option - it's likely I'm the only user who needs this j=
ust
now anyway so anything further would be a case of YAGNI.
