Add slf4j configuration for php, committers and scout

Because the slf4j.simple is not included "naturally"
by any of the features already in php, committers or
scout, include it explicitly here.

Includes revert "Don't add slf4j.simple to products that don't include slf4j already"
This reverts commit a196924.

Fixes #27
