annotate gamelib/engine.py @ 469:e0b11d684ee8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Reference gameboard.level rather than game.level where appropriate. Saving and restoring games appears to largely work now (even if the level of the restored game is different to the current one).
