[EDKT156][Closed] Re-ordered the build.xml files in the clean and cleanall targets...

[EDKT156][Closed] Re-ordered the build.xml files in the clean and cleanall targets.  For cleanall, some of the Jar files could not be deleted if the TianoTools cleanall target had been executed first - this is due to the classpath being set in the TianoTools/build.xml file.  All jar files will now be deleted when executing the cleanall target for build.xml in the Tools directory.
