Creates a JSON file for custom sprites and custom images.

To use, download the KeeperFX GFX Archives. Then put the extracted files in the correct folder and run jsonner.bat to get the json you want.
The JSON will hold the folder structure as present in that folder, and the sprite offsets are automatically set from the filelist txt files inside.

Example:
If you want to make a custom ghost, you want to download the default ghost and edit the images of the original ghost, and put that back in the game as a custom sprite.
You download and extract the gfx files then navigate to the /enginefx/sprites-32/creatures/creature_ghost/ folder inside, and put jsonner there. Double click it and get a json file for a ghost.
