Title: Update try-expression.

To conclude jashkenas/coffee-script#2900, this PR brings the try-expression into line with CS1:

* Allow parameterless catch.
* Imply `catch` only for a lone try clause (without `finally`).
* Allow empty body in catch and finally clauses.
* Don't allow `then` after `try` or `finally`.
