Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
quick frontends (app): added an "ignore_missing" argument to RemoveListener: normally an error is logged when removeListener is call on a inexisting listener, but sometimes listeners are added only in specific scenarios, and it may be handy to try to delete them without having to explictly check that they have been used.
