Add slf4j configuration for php, committers and scout

[jonahgraham]

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

@HannesWell this seems one way to resolve the problem I mentioned in #43 (comment) (part 1)

Yes this looks good.
Actually I expected that slf4j.api/simple will be pulled in from the eclipse/updates repo automatically.
Does the product contain any bundle that requires SLF4J?

AFAICT the bundles that worked (like cpp) pulled in slf4j.api/simple, but the others pulled in slf4j.api/nop without this change. I don't know how to track down the why though, so perhaps all packages (without logback) should have this slf4j.api/simple added to the product file?

If slf4j.nop is available in the SimRel repo then it is probably random if simple or nop is included, unless some feature also includes slf4j.simple.
So yes it would probably be a good idea to add simple explicitly where we expect/want it.
Should I provide a PR? slf4j.simple is probably enough. It will pull in the slf4j.api anyways.

Nothing with SimRel itself strictly requires what's provided by either one:

This thing is happy with different possibilities:

I will create such a PR, thanks for offering though. It woul d be great if you could review it at some point though.
