Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Rewrote the object serializing routines to use a "template" idea for loading an object from disk. This allows for multiple objects to load the same base object template but be unique on the scene AND have different values. Useful for say more than one gold stack on the ground with different gold values. TODO: fix the "spawn" console command.
