Conditional SQLite import

[multimeric]

Only imports the SQLite module as required, as documented in doit issue 153.

This is useful in cases where python has been compiled without sqlite support but users want to use a different backend (e.g. json)

Includes a small unit test for this requirement.

It's not building on Windows and I can't for the life of me work out why

The failure is not in your test... dont bother about it.
This test used to work but started to fail, not sure a change in a library or appveyor.

Thanks. Please add your name on AUTHORS file 😄
