Codechange: Clean up build industry window. (#10779) 

* Remove left-over code that treated an invalid list selection as 'fund
many', which is actually implemented as a separate button.
* Manual list management replaced with std::vector.
* Enabled state is only needed for the current selection.
* Selected index is not required only selected type.
