Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Now using the global MailAddonBusy to indicate MailOpener is busy, read comments in Core.lua for more info. Default status is now ?enabled without automatic mail opening? to let first time users look around before MailOpener messes up their heads. A StaticPopupDialog will be added later to ask if they want to auto-enable. When ?enabled without automatic mail opening? is on and you toggle the mail opening checkbox on, mail opening will automatically start.
