Audio Track Core Selection

[vertigo]

Using the "(havemulti|core)" option in the default selection rule allows for selecting/deselecting the core for audio tracks, but since it doesn't differentiate between a TrueHD core and a DTS-HD MA core it only works for one or the other. This is because TrueHD does not contain the core, and therefore needs it selected separately in order to keep it, whereas DTS-HD MA does include it, and so it's unnecessary to select it necessary. It would be very useful to have an advanced option to select the core for a TrueHD track and deselect it for a DTS-HD MA track.
