Django dev JSONSerializer is now based on json

Djando dev breaks Tastypie serialization. Tastypie uses Django
`json.JSONEncoder`, which was based on simplejson in previous versions,
but it's now based on json, which doesn't accept a keyword argument
`namedtuple_as_object` anymore.

So in Django 1.5 we need to pass `JSONEncoder` to json, instead of
simplejson

Refactor GenericResource resource lookups

GenericResource instances maintain a mapping of resource names to
resources. This allows them to limit urls only to valid resources,
and to construct appropriate resources without relying on
func_closures.
Allow no max limit on the Paginator.

0 is a valid value for limit. If there is a max limit, take that,
otherwise no limit.

Thanks to @dfryta and @Solvik for the reports.
Resource: consistently use Meta.collection_name when available.
