d9a8cb0d6a Don't accept user-provided tx values. 
This agrees with Datomic.  DataScript allows tx values, possibly to
allow reconstructing DBs from Datom streams, but appears to handle
user-provided tx values in the transactor inconsistently.

38545f6efc Add :tx and :txInstant to TxReport; accept :db/tx in transactor; allow to set :db/txInstant. 
The implementation of :db/tx is special and may need to change over
time.  We add it as a special ident, with value the current transaction
entity ID, specified per-transaction.  This works well right now but
introduces some (internal) ordering requirements that may need to be
loosened.

f25838a1eb Support :db/fulltext true. 
Internally, we use SQLite's FTS4 to maintain a fulltext_values table of
unique "text" values.  Fulltext indexed datoms have value v that is the
rowid into fulltext_values.  We manually maintain the map between rowid
and value in the transactor.

For convenience, we expose two views interpolating the real text values
into the datoms structure.

5d271454ac Don't replace keyword idents if the underlying field is itself :db.type/keyword. 
This is necessary to assert new :db/ident datoms.

9497d69b44 Respect :db/unique constraints; test upserts. 
This version includes SQLite-level unique indexes; these should never be
needed.  I've included them as a fail-safe while testing; they'll help
us catch errors in the transaction layer above.

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.
