Deletion of Merck Molecular Force Field

Comment: as notable (subject of multiple )...no MMFF is included in many popular molecular molecular-modelling programs and various independent secondary-source articles likewise state that it is popular/important and worthy of being studied and evaluated (rather that just published for others to use). See for example doi:10.1186/s13321-014-0037-3 and {{arXiv|1705.04308}}. I don't see promotional/ content, but if so that would certainly merit being cleaned up
