Add an 'is' operator (a la Python), and support object identity #526

We should basically mirror Python in all respects here, except that we won't have an is not operator with whitespace in it.

I'd also be fine with an id() built-in, for getting an object's "identity", probably a number akin to a memory address. is would basically be comparing such identities.
