Message:

BUGFIX: config::SaveMPQC() used molecule::DetermineCenter() which relies on the created bond structure, causing segfault.

When storing a newly created configuration file, the bond structure needs not be present yet. Hence, we created the function molecule:DetermineCenterOfAll(), similar to molecule::DetermineCenterOfGravity() just without scaling by masses. This new function is now used instead.
