Adds a new Difficulty Setting which changes how long each "second" lasts in a level. Off by default, but when on it uses full seconds instead of 0.4 seconds like in SMM2.
NOTE: The translations will need to be checked properly.
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)
