Tilesets listed twice in the options menu

[Chambs-15]

Describe the bug

Every entry on the list of Tilesets avaliable in the Options menu seems to be duplicated.

Steps To Reproduce

Go to Settings > Options > Graphics tab > "Choose Tileset" and check the list of possible options on top.

Expected behavior

Only one option for each Tileset avaliable.

Screenshots

Default options from a fresh install:

After downloading "UltimateCataclysm" Tileset, confirming there's only one entry of it on the "gfx" folder and rechecking the listing:

Additional context

"gfx" folder seems to only have one of each tileset, "options.json" shows duplicated entries.

This happens because both gfx dir and user gfx dir are pointing to same folder.
