libcifpp update

I just uploaded a new version of libcifpp (version 9) to salsa. Could 
someone with more powers than me please upload this to the NEW queue?

BTW, I decided to keep the old components.cif file in the data part of 
libcifpp even though I considered splitting out the file into separate 
files. After profiling I found that this adds at most 0.7 seconds to a 
run that needs component information and I thought it was not worth the 
trouble to re-implement this. If others do think this is still worth it, 
I will reconsider.

Thanks, -maarten
