Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Multiple quests now work. Added the item layer. Made movement more like diablo by allowing you to hold and drag the left mouse button. All objects are now loaded from a separate "allobjects" file. Specific item attributes are loaded from the map objects file (like position). This allows for the possibility of multiple instances using the same FIFE model.
