Provisional support for Express 2.

Add support for Express 2.0 `compile()` method.
This makes jqtpl compatible with Express 2.0.
Backwards compatible with prior versions of
Express, by virtue of leaving the existing
`render()` method untouched.

There are no new tests included, and I haven't
verified the old tests still pass, as I can't
get qunit to run on Node 0.4.2... :(
