Bug fix for PDmaker for positive formation energy detection.

1. Completely new json encoder and decoder that support serialization of almost all pymatgen objects.
2. Simplification to Borg API utilizing the new json API.
3. Bandstructure classes now support spin-polarized runs.
4. Beta classes for battery (insertion and conversion) analysis.
