When total envelope costs are used, it makes it look like packaged envelope + HVAC measures are much more expensive than HVAC-only measures (not packaged with envelope), even though envelope upgrades do occur in the baseline alongside those HVAC-only measures. Setting to an incremental cost accounts for this and effectively represents envelope+HVAC costs as a somewhat more costly version of the HVAC-only case that also delivers operational cost savings.

Switch to adding incremental envelope costs in pkg_env_cost
3ddcdf8 
When the user specifies the pkg_env_cost option, only the incremental (vs. total) measure envelope component upgrade cost vs. baseline envelope component upgrade cost is added to the overall HVAC+envelope measure cost. This ensures that when users define HVAC+envelope measure packages and compete them against HVAC-only measures (where baseline envelope costs will not be reflected), the competition fairly reflects the incremental cost difference between two those measures (vs. representing the full HVAC+envelope cost vs. the HVAC-only cost).

Addresses #465.
