This reverts commit 38c04dbd.

Made sure that the downloaded kieker jar will be copied to the classes directory during compiling (the redundant jar file is unnecessary now).

I removed the synchronized modificators at most of the bean's methods; Under normal circumstances it should not be possible that two tabs or browsers share the same view scoped bean.

Code comments; Refactoring and code quality within the CurrentAnalysisEditorGraphBean; Solved a minor bug by escaping the names of the components

#685;Added guava to the project; Added another example; Solved a minor problem within the flow editor.
