Sorry for the large commit, but this reorganizes and unifies some of the files naming conventions and adds some new ones. Now, a basis set has the correct suffix. If it is molpro format, it is XXXX.molpro, etc, same for ECP format.
I add for all of the ECPs a new file format, namely nwchem basis sets and ECPs. This is for use with PySCF, which uses the NWChem format. Now a GAMESS/QuantumPackage user can grab the .gamess files and a PySCF user can grab the .nwchem files since pyscf parses this format.
