25C: Even more tracks 🎧🎼

So I ended up adding a lot more than I'd originally planned for version 25C. I was only going to create the playlist for ROT then add the rest of the tracks to it - ambience and drones, basically - but after revisiting the old prototype project which most inspired ROT - an unreleased project internally known as FogTown - I decided to bring all of those tracks in as well. There were a lot...!

There are also an extra few random tracks thrown in, including the track from the recently released climax (?) to the 212X trilogy (?) 2125.

Those changes in full:

• Fixed "8"s in the font image to match those seen in tracklist images
• Added additional info to the Controls screens to indicate that "B" is also a "Back" button as well as "Stop"
• Added left/right arrow graphics to either side of headings on Underlier Series pages, plus new track
• Added new tracks to Misc.:
  • The Frogs Have Boiled from 2125
  • Three variants of [new for '25 #2...]
• Added ambient tracks from ROT and gave it its own playlist, also added tracks and created playlist for unreleased GBS survival horror test project FogTown
  • Adjusted playlist selection menu to accommodate these
