Official SQLite WASM Branch

Woot! It's lovely to see someone other than oneself hype one's own code ;).

The first beta of the wasm/js bits will be officially released along with sqlite3 version 3.40. We've been working on them since (IIRC) May.

i feel compelled to point out, though, that github provides only a read-only mirror of sqlite. The official sources are at <https://sqlite.org/src>.
