Fix client-server event schemas: remove age, dedupe fields

This commit adds support for event schema examples to have references to help reduce the chance of fields being forgotten. This also helps reduce duplication of fields, allowing for a more consistent spec that uses the same values everywhere.

This also removes both `unsigned` and `age` from the examples as per:
* matrix-org#1524
* matrix-org#630

Finally, this replaces "localhost" in the examples with an example domain. This is really just a nitpick thing on my part where seeing a "real world" domain is preferred. 

Fixes matrix-org#1524
Fixes matrix-org#630
