Bug found when toggling TrustInfo between namespaces v2 and v3. Fixed.

Additionally. As mentioned in post #21. It is possible to get two TrustInfo entries if merging multiple manifests, one using v2 and one using v3, depending if v2 exists in the selected manifest. Also mentioned in that post, you can simply unselect the one you don't want. When selecting the menu to toggle the namespace and 2 or more TrustInfo elements exist, the first element is the one that gets toggled. At that time, the others will be flagged so you can delete them via the tree node's context menu (right click)
