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.

The functions add_dependencies() and set_global() are convenience
methods that allow you to modify the global namespace while
the current file is running but then have it be cleaned up
by index.js when you're done.

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);

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.
