This updates the commentary on the python client, now that it can
work with StoryBoard instances that use self-signed certificates.
It also removes 'examples of delete commands' from the TODOs, as
we don't want to make it easy for passers-by to copy-paste a command to
delete data in bulk without any understanding.

Otherwise, the user will get this error:
`AttributeError: 'list' object has no attribute 'iteritems'`
which is rather difficult to track down.

Now a user can more easily find out how to update StoryBoard via the
python client.
