Fix formatting indices present in python 2.6.
Change the way the tests.cluster file is generated
to handle multiple runs of the same test. We
were appending more jobs to the same file, thus
causing collisions. References #4222
remove the dumb print output statement... #4223
Add check in CrackFrontData for whether crack front node exists, also fix problem with infinite loop for crack front with only two nodes refs #4161
Make DomainIntegralAction create VectorOfPostprocessors for 3D J-integrals closes #4228

Also convert two of the tests over to checking the CSV output generated by this.
