Title: Fixed issue with CrystalReports when real log4j is not on classpath

Crystal Reports (version 11.5.8.826) will not run with log4j-over-slf4j because it needs 2 classes on classpath: Layout and SimpleLayout.

First one was already added. Now I also added the second one.

Crystal Reports code is obfuscated I can't understand how Layout or SimpleLayout is used.
I tested and it seems that only the presence of these classes on classpath solves the issue.
