CSRF validation will only be applied to POST requests, so let's only load .RAW_CONTENT in those cases

Fixes #35 - Import json from django's built-in package (Does cleverness in determing best lib to use)

Generic permissions added, allowed_methods and anon_allowed_methods now defunct, dispatch now mirrors View.dispatch more nicely

Better error handling for Basic authentication. Catch exceptions that could be thrown due to malformed input

Use cleaned_content instead of raw_content when generating a form instance for the DocumentingTemplateEmitter. This allows the form to be prepopulated with the resource's existing values.

Turn streaming request parsing back on for 1.3.  Fix CSRF which was breaking it.  It's really not at all obvious if we need to byte limit the stream that we hand over or not.
