Minor fixes tonight

[Tsagoth]

You should no longer see the Claim flag, or the other planetary object actions for stars.

Let's hope this puts an end to the practice of dropping Colony ships into the sun.

Edit: Also, Mammoth Array, Dread and SuperDread are now marked as Warlord only. The client will still show you these ships for the other specialties until a new update is released, but the server will deny construction attempts if you do not have the specialty.
