Daniel Dulaney 7fbbb6438d Implement Bindable for Option<T>
Option<T> is generally used to represent either a T or a null value. In SQLite,
it makes sense to model this as either a regular T binding (when the option is
Some) or a regular NULL binding (when the option is None). This commit
implements Bindable for any Option<T> where T is already Bindable, allowing
those Options to be used directly with statements, filling in NULL where needed.

No new unsafe code is needed. Tests are included.
