Webcredible action - Order of A-Z lists

The tip page can/can’t bring items list were sorted alphabetically, but
where some are links so they would all get put at the start (the sorted
links followed by the plain text items). I have added some more sorting
logic so both link text if available and plain text are considered.
I have applied CSS columns to the lists instead so they read
alphabetically vertically rather than horizontally now. This will only
work in IE10+ and decent browsers, earlier IE fallback for horizontal
grid layout has been removed.
