These are most of the changes needed to finish my content. I still want to add a few things, but none of it should be essential for game flow. I'm not sure how Scott's 'fight the shooter' content is activated yet so we might still need to add the necessary triggers for activating his content once the player runs from the room.
removed the commented out code that was not needed in getOutOfBuilding.js and uncommented the code that was needed in activateShooter.js
Added content for student runs past.
Slightly more space-efficient saving
Save only the attributes of triggers that need to be saved.  Down from 11688 chars (unescaped) to 2166, which might be enough.
Remove the variable names from the save, down to 1982 chars unescaped
Got rid of "lives": on triggers, down to 1582 characters
