[hibernate-dev] Logging dependency cleanup

[Steve Ebersole]

I thought I remember someone (Brett?  Strong?) going through an cleaning 
up references to logging libraries we no longer use.  But I still see 
entries in libraries.gradle in master for:

             slf4j_api: "org.slf4j:slf4j-api:${slf4jVersion}",
             slf4j_log4j12: "org.slf4j:slf4j-log4j12:${slf4jVersion}",
             jcl_slf4j: "org.slf4j:jcl-over-slf4j:${slf4jVersion}",
             jcl_api: 
'commons-logging:commons-logging-api:99.0-does-not-exist',
             jcl: 'commons-logging:commons-logging:99.0-does-not-exist',

Did I just dream this?
