Autocomplete the same as django-admin

[ryanhiebert]

From Discord:

django-admin fires up suggestions/autocompletion, which seems to be lacking with django-cmd

$ django-admin [hit tab here]
cleanup                    -- remove old data from the database
compilemessages            -- compile .po files to .mo for use with
createcachetable           -- creates table for SQL cache backend
createsuperuser            -- create a superuser
dbshell                    -- run command-line client for the curre
diffsettings               -- display differences between the curre
...

Two people report that they don't recall having to explicitly install anything for the completions to work.
