Need a way to keep scripts consistent between the user view and the production server

[RTimothyEdwards]

Currently we have no way to check if scripts in caravel, caravel_user_project, and mpw_precheck run the same way for the user as they do on the production server. This was highlighted recently when I discovered that the script for "make ship" in caravel_gf180mcu was missing a critical line that could cause invalid final GDS. We need to be able to catch such discrepancies.
