[totem/wip/hadess/no-properties: 5/6] main: Add API to track the current "main page"

[Bastien Nocera <hadess src gnome org>]

commit 7d6ce5fccffffe47e8e6b4719782347b50ea7dcb

    main: Add API to track the current "main page"
    
    The "main page" is either "grilo" when browsing for content, or "player"
    when playing something back. This property might be of interest to
    plugins that only want to work in one of those 2 views.
