updated the Dettmann reference

to Tingnan:
1. a while ago you used JabRef on siminos.bib. For me that is a problem,
as siminos.bib is a copy from repo siminos, to be edited there but not
here
2. I've renamed your version siminosTZ.bib - if you had added new
references to it, please save them someplace where I can copy them (or
add tem to siminos/bibtex/siminos.bib repo yourself, then remove
siminosTZ.bib
3. Dettm14.bib is the complete reference list from Dettmann's review, we
might need some of those for our paper.
