cca5010671 Part 1: Fix testing errors. 
Some of these were just typos, but `with-open` was fatally flawed on
CLJS (we couldn't call `.close` at all), and `deftest-async` was hiding
all failures (due to a typo).

900e77862e Implement database on top of SQLite connection. r=rnewman 
We would prefer to talk about a knowledge base on top of a database, but
all the Datomic and DataScript code (and symbols, like :db/add, etc)
refer to the "database of datoms", so let's roll with that nomenclature
and try to be specific that the persistent storage-layer is SQLite.
This will become more clear when we actually use SQLite's unique
capabilities for text indexing.

d5cfbeaa45 Add tempfile and with-tempfile to CLJS. 
We already have a nice library like this for CLJ (tempfile); this builds
the same thing for CLJS, using Node.js's tmp.

0a312b4f40 Add an async and async testing framework. 
This is a well-worn idea: use a `promise-channel` of `[result nil]` or
`[nil error]` pairs.  The `go-pair` and `<?` macros handle catching
exceptions (important, given that synchronous CLJ code expects to throw
rather than return an error promise or similar), allowing code like:
```
(go-pair
  (let [result (<? (pair-chan-fn))]
    (when (not result)
      (throw (Exception. "No result!")))
    (transform result)))
```
to be expressed naturally.  These are the equivalents of `async` and
`await` in JS.

The implementation is complicated by significant incompatibilities
between CLJ and CLJS.  The solution presented here takes care to
separate the macro definitions into CLJ.  Sadly, this requires
namespacing the per-environment symbols explicitly; but we hope to
minimize such code in files like this.

The most significant restriction to this approach is that consumers must
require the transitive dependencies of the macro-defining modules.  See
the included tests (both CLJ and CLJS) for the appropriate
incantations (for pair-chan, core.async, and test).
