First cut at a PDO driver for SQLite 3.x

Features:
- native prepare/execute and bound parameters.
- finally supports binary data (via bound parameter api)
- full unicode/utf-8 support

Missing:
- UDF functions
- authorizer hooks for safe_mode/open_basedir restrictions

You need to download, compile and install sqlite3 yourself; we're not bundling
it (at least, not yet).
