Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Introduced the ViewportController that sits between the application and the Scene2D to handle the trackers and measuring tools. This is a work in progress. The Scene2D is no longer an observable. Message sending is managed by the ViewportController. Move some refs to shared and weak to prevent lifetime issues.
