GUI: auto-replace card images in gameplay to specific sets (and more)

Original problem: opponents can use old or rare card versions, so you don't have images for that card or you like another images.

It's a card images replacement on client side only while playing games (example: game shows card from old set, but uses image from the new). Deck editor must show original images.

Most requested feature: replace all lands by full size version from specific set.

TODO:
* [ ] need to research: is it possible to implement with current images buffer architecture.

Card images mode (combobox with one selection):
* [x] Show all available images (default);
* [ ] Show images from basic sets only (ignore promo sets);
* [ ] Show images from latest basic sets (ignore promo sets, use latest released sets);

Addition todos/ideas for card images replacement rules (checkboxes to enable-disable):
* [ ] Replace all basic lands to specific set (set name to enter);
* [ ] Replace missing images by existing images;
* [ ] Download mode to download latest cards version only (some type of optimization);
