Local Environment: Add SQLite database to hidden wp-now directory in 'wp-content' mode

[danielbachhuber]

A couple of users have been thrown aback by the wp-content/database directory created in their Git checkout.

For 'wp-content' mode, it would be preferable to use a SQLite database from the hidden wp-now directory. It might be a little tricky, though.

Done is:

• In 'wp-content' mode, we're no longer creating the SQLite database in the user's project.

We should do this for 'wordpress' mode, too, as it also creates an SQLite database if wp-config.php does not exist.
