Fix build failed introduced in rev. 8521
Reason: I used org.apache.commons.collections.keyvalue.MultiKey class which is in commons-collections API but not included in C/STools.jar, just in JasperReportsTools.jar
Action: now C/STools.jar include commons-collections-3.1.jar. I removed from JasperReportsTools.jar
