Fix T61446: (second part) Some items in editor and mode selectors are not translatable.

That one is utterly ugly fix really, but unfortunately a proper one
would require some changes to our RNA (or more precisely, pyrna) code,
so that when we subscript a dynamically generated RNA collection, the
item is somehow duplicated (and probably 'assigned' to its py object?),
before the temp RNA array memory is freed...
