Java 9 module(Jigsaw) with old Slf4j API.

This version is a patch for applications implemented with Java9 module(Jigsaw) but using Slf4j version 1.7(which is not a java 9 module), for example Spring boot doesn't allow to use Slf4j 1.8.x(org.slf4j module).

Just add it to your dependency then you can use the slf4j module in your application.
