By shipping with our own sqlite source file we never depend on SQLite being
installed, and we don't have to go on a wild goose chase in esoteric
directories for every platform we wish to support.

Due to not having to bounce in and out of JavaScript, this should make
fetching results from SELECTs significantly faster than manually using step to
iterate over the results.

There was an off by one bug in the way bindings for strings were happening. A
NULL literal was being appended to string bindings. Thanks to @carter-thaxton
for reporting it.

Column data (name and type) should only be allocated once.

Add some options to preparing a statement. If the lastInsertedID and/or
affectedRows options are specified, those values will be looked up after every
step.
