Remove C3H6OOHx-yO2 things and add C3KETxy things to Dooley known species list.

Franklin told me what he thinks the C3KETxy species are, and it agrees
with what we think they are from the decomposition pathways. I can't understand
the formation pathways, which means perhaps we got the precursor molecules
wrong... so I'm removing them from the list and we can try again.
