fix for the which[0]=1 option -> reslice 2..n images
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.
rf: refactored automatic file name generation in base class
Segment in SPM interface throws error.
In Segment, include bias-corrected output only if corresponding save_bias_corrected boolean is True.
This prevents to throw an error when save_bias_corrected is set to False but Segment still looks for a created bias-corrected output.
Add deprecation for old output variable modulated_input_image in Segment (to be replaced with bias_corrected_image) and removed exists=True for outputs that are predicated on input settings
