[Q-CHEM] Build Q-Chem

add remkey without re-building whole q-chem

$ rm $QC/config/rem.conf
$ qcmake rem_config rem rem_input
$ rm -f $QC/qparser/*.o $QC/libgen*.o
$ qcmake qparser.a libgen.a
$ rm -f $QC/<probably program>/*.o
$ qcmake qcprogall


local copy of qcaux

As suggested in README.QCAUX: "It is recommended to store qcaux locally, especially drivers, as loading appears to be pretty intensive and puts a heavy tax on NFS, and may stall Q-CHEM when network is flaky."
