fix for the which[0]=1 option -> reslice 2..n images
Added FSL output type NIFTI to dmri mrtrix example
fix: avoid stopping of nipype-workflow caused by temporarily suspended LSF-jobs, And changed logfile of lsf-jobs from <lsf_jobid>.out to <scriptname>.log
3drefit does not accept -prefix option, since it operates on its own file
now it will work if you give the same out_file name as in_file name
however if you give no out filename it might not work if your
infile is a .nii or .nii.gz since afni will make briks

Cline bug name_source
fix: reverted fix while keeping changed meta tag.

@bpinsard - reverting the fix while keeping name source. too many doctests started failing. the intent of spec.genfile or spec.name_source is when the input is undefined, not when its defined.
Added support for non standard return codes. For example when a non zero
code is returned but the program has run successfully.
Make WarpTimeSeriesImageMultiTransform not crash due to wrong return
code.
fix: outputs never sets outfile if defined.
