skin engine: Add tags to display Quickscreen Items

A set of new tags for themes that allow them to display a quickscreen item's name or value like what is displayed on the default quickscreen.

There are 8 tags in total, 2 for each direction or "item".
One type of tag displays the setting name, while the other displays the setting's value.

All tags output an "ERR" string if no valid setting is found for that item.

Quickscreen Item name tags: %QT, %QR, %QB and %QL.
Quickscreen Item value tags: %Qt, %Qr, %Qb and %Ql.
