handling of broken games? undo to fixed / archive game; send message to API to mark as broken in DB?

• make it possible to undo to the last working action?
• add button to archive broken game? (this would at least be nice if the game is already pinned and is encountering an error)

[michaeljb]

If providing button to undo to last working action, maybe provide another button to undo to any action so they could return to the "branch" they were on before the game broke?

Full visualization of action tree would be cool to allow "hopping" b/w branches or even attempt a "rebase", ie, wound back to last working action, fixed whatever was broken, now please re-apply actions X thru Z, etc

Would be cool if we could also mark it as broken in the DB, and that would be unset whenever a valid action is added to the DB, maybe the field would be like browser_exception or something
