Load from any directory

## Positives

- No longer has to be located in the game's source folder under "lib"
- That's pretty much it.

## Negatives

- If a directory containing light world contains a dot in its name, will break

## Fixes (?)

Now there are two ways I see to fix the problem of dots in folder names (other than adding folder checks which I didn't even think about until just now):

- Make sure light world is only loaded with slashes in the path, and remove the dot replacements from the code.
- Just don't have dots in the path.
- Add in code to check for folder existence to check if using dots in the path (which is more complicated than needed in my opinion).
