This PR changes the End Final Castle to use the Special visuals when the level is in the SMBS campaign.
This is primarily for the Level Editor / Custom Levels and isn't really necessary for the main campaigns. Hence the added check to see if the Level Editor is used.
This was supposed to be a quick quality of life addition for the Title Screen that applied the save and theme to the menu, but then I discovered a new bug I had to bypass with the character palette when doing it. So I ended up doing a bit more related to the Title Screen as a result.
I also *had* a function which checks for the number of valid folders within the Pck to see how many worlds there are, but I think it might've been a bit slow so I replaced it with constant values.
- Save for the currently loaded campaign gets applied on startup
- Backing out of World 9 and over keeps you on said worlds at the title screen
- Added Skyland and Volcano to SMB1 themes since it shares most of its themes with Lost Levels
- Fixed Title Screen Stars for the Volcano Theme
- Fixed Disclaimer Screen not playing Sound Effects loaded from the Resource Pack
- Fixed Quit Dialog not playing Beep.wav loaded from Resource Packs
- Fixed the Campaign Icons not loading the Resource Pack textures (in fairness the only icon applicable is the Custom Levels one)
