levels: rename Episode 2. (#1328)

Closes #1327.

Brief summary:
- the bland description feels really out of place with its straightforward description against "Outpost Outbreak" and "Event Horizon".
- nothing in this episode looks like a "military lab".
- what it *does* have is an overgrown-ruins theme with a bunch of AGM tech overlaid on it.
- the old E2M1 even was explicitly named as "ruins".
