Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Enabled ServiceContentList to call its callbacks when its value changes. Tried to fix some other bugs, but this is not a very clean commit, due to wanting to make some big changes to enable better use of invariants next.
