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.

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.

This version includes SQLite-level unique indexes; these should never be

us catch errors in the transaction layer above.

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.
