investigate need for RequestContext

[oberhamsi]

a RequestContext takes the request as the first argument and automatically populates the Context with a few variables according to the TEMPLATE_CONTEXT_PROCESSORS

this is how they get things like user, permissions, mediaUrl/staticUrl, messages and csrf protection into their templates.
