Ning Jing Battleship equipment

Is your feature request related to a problem? Please describe.
Empire v3.06 v13 Catalogue, Ning Jing Battleship. Unit cannot deselect a Heavy Gun Battery mount to select a generator per pg.17 of the Empire Orbat. When selecting any Chinese Flagship as part of a Battlefleet - excluding Empire Faction Battlefleet - selecting an escort, aside from a Chita Escort, is reported as a roster error.

Describe the solution you'd like
Add "None" selection to Heavy Gun Battery selectors for Ning Jing Battleship to allow selecting generators without error. Remove error when selecting standard escort tokens for Chinese flagships.
