Remember when Lach recorded their live reaction to 2.2 so far? Do you recall what the reaction to ACZ3 was?

If you don't, the reaction was "WHAT?? Why is he here? This is GREAT but, what??" And while the reaction is on the positive end of things, it's stll clearly not advisable for our defining Big Reveal of the already huge update.

To this end: Here is a mini cutscene! https://cdn.discordapp.com/attachments/428262628893261828/626207624043429898/srb20005.gif
* He's digging through Eggman's trash.
* Clearly doesn't expect to see you!
* Ready for a fight all the same.
* You can attack him during the mini cutscene if you're impatient.
* Skipped if you give him MTF_AMBUSH.
* Requires new assets (including map) to test, but I'm not ready to make a MR yet because I have other thoughts first.

Also, since I was poking around in p_enemy.c, I fixed A_Boss1Laser's issues (not working with direct 2.1 port states and having the weird secondary attack).
