Vmitnick/crema headlights

This logs an additional headlights event when assets are generated for a PSD where the user used Crema to set up generator, or for a PSD where the user didn't use generator, so we can compare the two.

To avoid having an even for every asset generated, I'm currently limiting it to a single one of each of these events per PS session, but might change that.
Yeah, it would be best to just revert that last commit. (It also introduces lint errors.) If you do that, I'll merge it!
