Shopeditor: Item Buyability Broken due to Cache State (#1621)

This pullrequest fixes the issue where items (not weapons) had the wrong
state if a custom show was created. This means that they were always
marked as selected, even if they weren't. This was due to the caching
being done too early, before the items were initialized at all.

The issue didn't exist for weapons because their setup is done in the
engine before any lua init code is executed.
