htsp: #2206 Do the same thing for list view also.

Notes:

I'm not sure in javascript how to apply this poperty sorting criteria only for sources of type

			  "tvchannel", "iteminfo/tvchannel.view",

However this change was tested in my own custom OS X build and it does not seem to break other list regular views which are not of the `tvchannel` type.

@andoma  I need you to pls merge upstream since I can't compile for PS3 architecture myself. Many thanks.
