Support SQL dump import (to enable complex setups, e.g. for WooCommerce) #692
Description
There's no easy way to set up Playground for a complex plugin like WooCommerce:
- WXR doesn't support custom tables
- Preparing an entire custom SQLite file is tedious and may not be portable between WordPress versions
The ability to import entire SQL files was requested by multiple developers. Let's support it, or something equally expressive and convenient.
