Fixes NREL/SAM#1876

Use following labels as much as possible

monthly_energy "Monthly energy in Year 1"
annual_energy "Annual energy in Year 1"

* `monthly_energy` "Monthly AC energy in Year 1"

* `annual_energy` "Annual AC energy in Year 1"

* Fix capitalization as convenient

* Don't change labels for SWH, and for some CSP models that have long labels, or for Marine Energy, etc.
{ SSC_OUTPUT, SSC_ARRAY, "monthly_energy", "Monthly energy", "kWh", "", "Monthly", "", "LENGTH=12", "" },
{ SSC_OUTPUT, SSC_MATRIX, "annual_energy_distribution_time","Annual energy production as function of Time", "", "", "Heatmaps", "", "", "" },
{ SSC_OUTPUT, SSC_ARRAY, "dc_monthly", "Monthly DC energy", "kWh", "", "Monthly", "", "LENGTH=12", "" },
{ SSC_OUTPUT, SSC_ARRAY, "ac_monthly", "Monthly AC energy", "kWh", "", "Monthly", "", "LENGTH=12", "" },

This is probably for a different issue, but I believe ac_monthly and monthly_energy will always be the same. Do we need both?

This is probably a vestige of the original implementation of PVWatts. I don't think we need both in SAM, but removing ac_monthly may break code out there in PySAM or other apps that call the PVWatts library.
