prepare_connection() plugin hook should accept optional datasette argument

[simonw]

I want to build a plugin that allows users to configure certain database columns to be "masked" - so the password column on a users table is never revealed, for example.

To do this, I need to use the conn.set_authorizer() SQLite mechanism. So the plugin needs to build off the prepare_connection(conn) hook. But that hook doesn't currently get passed datasette so it doesn't have a way of looking up its plugin configuration!

While I'm at it, the hook should accept an optional database name argument as well.

Done. Updated documentation is here: https://datasette.readthedocs.io/en/latest/plugins.html#prepare-connection-conn-database-datasette
