Save literals in the object graph data?

[foolip]

Maybe we're already doing this, but it'd be neat if we save any literal values (strings and numbers) that show up in the object graph. In particular being able to see length of various things and navigator.vendor and navigator.userAgent would be neat, even if not exposed in Confluence.

From a look at the data files yesterday, we're not doing this, but we do separately save navigator.userAgent.
