Add validation for the cache backend setting.

If users type the wrong thing into the cache backend setting in the admin site,
it can save to the database, which will then cause any request to the site to
generate a traceback. This is particularly annoying because settings are stored
as a big JSON blob, so it's not even easy to fix.

This change adds validation using django's parse_backend_uri--if the form can
parse it, we know that this won't cause problems later on.

 








  


 
 

  
Tested in devserver by specifying a bogus cache backend URI.

Should there be another line break here?

    Hey David,

This looks good to me.  Just one style issue, and a question.

Thanks,

      Not here, but I did add one too many lines below. Will fix.

    I notice that this function is never called - am I correct in assuming that this will be automatically called via Django magic?

      Yeah, django calls clean_* for each field, if it exists
