WIP Omega Event

So this isn't working very well. It's halfway there and worked exactly once with what I can only describe as a cosmic ray event.

Here's how it's intended to work: Right as you open the Card Key door, Omega comes barging through, having previously been fighting with Giovanni.

The walking and stuff seems to work, but there are three issues:
- Omega's battle doesn't start, causing a softlock. `call TalkToTrainer` seems to be the iffy point. Note that this code is usually used when talking to a static entity.
- The music bugs out as Omega walks over; this may be linked to the above problem.
- Once these issues are alleviated, Omega will have to disappear, but this isn't a massive deal.

Also includes a dev door in Red's room to easily access the event, and minor code cleanup with Viridian Pre-Gym and Oak's lab - just unnecessary comments.
