Select from multiple available texture sets

[GrimPixel]

Is your feature request related to a problem? Please describe. There are multiple available textures sets, for cards, tiles, dice, and so on. For example, different card patterns from GNOME and KDE, with different config.cfg, stack.cfg settings. As there are at least 44 available texture sets for French-suited playing cards, they are not supposed to be simply created as an asset pack, because they take too much room in the selection list. The current solution is having subdirectories for such texture sets in the corresponding card or token directories, with one of them set to be the default and moved to its parent directory.

Describe the solution you'd like Add an option to select a texture set from multiple ones to be loaded in game.
