cache_page decorator doesn't work on callable classes — at Version 1

Description (last modified by Russell Keith-Magee)

The cache_page() decorator works fine on views, but fails if you use it on a callable class::

class MyView(object):
    def __call__(self, request):
        return HttpResponse()

If you try to wrap this view in urls.py ( cache_page(MyView(), 60) ), you get an error saying "MyView doesn't have attribute __name__". cache_page uses the __name__ attribute to build a cache key, but classes dont have a __name__ attribute. cache_page should also check for __class__.__name__ (or some similar key with a per-instance feature) to allow for wrapping callable classes.

This is a problem for 1.2, because feed views have been moved to a class-based structure, so it is no longer possible to cache feed views using cache_page().
