Allow Aeon T2 Shields to Upgrade to T3 Shields, however make it less efficient than reclaiming an existing T2 and rebuilding a T3 over it's wreck.

Give Seraphim support commanders a RAS upgrade path.

Add a "Hive" equivalent for both Aeon and Seraphim - ideally, they're worse than the Cybran/UEF versions, but it seems an immense oversight that in order to be effective in team games everyone spams the Cybran/UEF player(s) asking for donation T2 Engies.
