vcmi/lib/filesystem/ResourceID.h
Ivan Savenko dd73573c5c - vcmi can now calculate crc32 checksum of a file
- reorganized internal filesystem structure - all files from one mod are
now grouped in same FS node
- modhandler will now calculate crc32 checksum for each mod
- modhandler now knows validation status of each mod

todo - use checksum to determine mods that have not changed since last
start and disable validation for them.
