These versions result from testing on production galaxy.  Note ercc_se and wsc_pe versions may never be run.
Gave all step init params defaults to simplify simple version lookup that is done by galaxy.
Added 'duration' to steps and tools.  Added newline to json dump, so that (hopefully) galaxy no longer thinks this is binary.
Eliminated fastqc wrapper and put code in step, since it should only ever be used there.
Fixed the PASS/FAIL check at the end.
