EnergyPlus Python Transition 0.7

Nearly done. Includes all 8.5 to 8.6 transition except the extensive daylighting changes (and the EMPD calculation isn't fully implemented). Also need to verify all output objects are handled during transition before it's really ready to run. That, plus lots of testing, and a look at the runtime performance, are coming next. That is followed by figuring out final user packaging.
