Always display sorting logic in tags, regardless the display mode

[acelaya]

Summary

Currently, it is possible to sort tags only when using the list display mode.

Also, in mobile devices not even this is possible.

So the following changes to cover all cases.

• Move sorting logic to the parent component, and pass the sorting and icon generation functions down to the table component.
• Display a sorting drop-down next to/under the mode drop-down when using cards mode, or when using list mode in mobile devices (or maybe always and that's it).
