Sample-check brings in slf4j-simple dependency

https://github.com/gradle/exemplar/blob/master/sample-check/build.gradle.kts#L15-L17

The problem with this is that it collides with Gradle's own SLF4J implementation, producing the following output whenever an integration test is executed:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [file:/Users/lptr/Workspace/gradle/gradle/out/production/logging/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/lptr/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.16/f0cacc3d21e1027c82006a7a6f6cf2cad86d2a4f/slf4j-simple-1.7.16.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.gradle.internal.logging.slf4j.OutputEventListenerBackedLoggerContext]

I guess it should be up to the user of this library to decide what SLF4J bindings they want to use.

Looks like the dependency on SLF4J is mostly removed in master and should be fixed by releasing 0.5.0. I guess the libraries should be removed from Dependencies.kt as well, but that's not relevant to fixing this issue.

This is fixed in Exemplar v0.6.0
