Allow addons to set path and size of the currently playing file

[pannal]

When playing a file using an addon, such as Plex4Kodi or PM4K, the file path that the opensubtitles addon sees can be a stream URL, resulting in not-as-good query hinting when searching for subtitles.

Allow proper filename and size hinting by utilizing a global infoLabel in the "videoinfo" realm.

Addons can set it like this:

xbmcgui.Window(10000).setProperty('videoinfo.current_path', path)
xbmcgui.Window(10000).setProperty('videoinfo.current_size', str(size))

And the OpenSubtitles.com addon will read it if it's a stream URL.
