added namespace fetures to filebased cache

[xinbin <xinbin@…>]

In my project, I will generate more than 1000,000 cache files to avoid the list page querying database. So many files lying in a single directory is not a good thing.
I begin to think if there's a way diving them to different directories, just like namespace. Unluky, I found nothing in google. I beigin to modify the core code.
Finally I succeed, the changes are in a file (D:\Python25\Lib\site-packages\django\core\cache\backends\filebased.py):

1. remove urllib.quote_plus to the ky;
2. create dirs due to namespace.

But I think it will be great if offical adds the feature.

clarifying the ticket -- #13795 adds "namespace" features for most caches, but this is specific to filebased cache backend.

I may be able to pick this up for 1.4

This appears to have been done at some point, django computes the md5 of teh key, and creates sub directories for teh first two, and second two characters of it.
