Also adds a custom rule to eslint. Since the recommended way of extending
eslint is to create plugins as standalone npm packages, the separate rule
is published as 'eslint-plugins-empty-returns'.
Fixes#8669.
We create a blueslip error for undefined keys in Dict. This led
to a straightforward change in the unit tests for Dict. For the
unread test, to avoid the blueslip error, we had to be more specific
in setting up a user in one place, but this reduced our coverage,
leading to another small test being added.

The exceptions were cryptic before, and they were inconsistent with
the fold_case: false behavior.

This is like Python's dict.setdefault. I don't love the name, but
the consistency is nice.
We have lots of places where we do things like:
if (! dict.has('foo')) {
dict.set('foo', []);
}
var arr = dict.get('foo');
arr.push(3);
We can now write:
var arr = dict.setdefault('foo', []);
arr.push(3);

keys() and other methods that implicitly return keys return the
casing used for the most recent set()

This means that we no longer need to unmunge keys at the expense of
having to store the original key.

Dict.each() allows to iterate through values and keys of a Dict.
The callback function is passed value as the first parameter to
be similar to _.each()'s calling sequence.

There are also one or two places we don't need to use it for security
purposes, but we do so for consistencey.
