ReArrange throws UnsupportedClassVersionError

[Matthias Schoettle]

It seems that the layout lib was compiled with Java 7, but we currently use Java 6. This leads to the following exception when trying to run "ReArrange":

Exception in thread "Thread-6" java.lang.UnsupportedClassVersionError: org/tigris/geflayout/sugiyama/ram/ClassStructuralProperties : Unsupported major.minor version 51.0

It should be sufficient to re-compile the layout lib with Java 6 (see touchram-libs repository).

Updated source wasn't committed to repository (i.e., packaged JAR and source is not the same), therefore we remove the arrange button until this is resolved.

ReArrange not used anymore.
