Inventory Dialog Fix

This was a bear to track down...

Fixes a bug that can cause incorrect tabs to be pre-selected (possibly causing a crash) when the Inventory dialog is re-invoked. (Triggered when the new dialog instance is missing some tabs present in the previous instance.)

Fix: Previously selected tabs are now carried over from re-instantiation by matching the "kind" field instead of by tab number, with special handling to ensure that all tabs are selected if the "all" tag (if present), was selected.
