- minizip library is now part of sources, located at lib/minizip - cmakefiles will compile minizip as dynamic library (Note: only 2 files used by vcmi are included in minizip.so) - zip files can be loaded similar to other archives via filesystem.json - mods can use Content.zip instead of Content/ directory. Files in directory will replace files in archive.
