capturing fleet base and orbiting mobile base

[siyoa]

fleet base ... never got an option to interact with it the same way as if I capture enemy ship, cannot give it to my scientists to extract and reverse engineer those pesky vindicators

orbiting Tinker's mobile base ... it is not treated as a ship and the same happened as with fleet base, no dialog box for reverse engineering ... I captured one when it was as a ship, not orbital structure (in my previous game) and I got an option to reverse engineer
