Minor bugfix for the minor bugfix. :3

Minor bugfix.

Added compatibility with Nomads: the Wandering Void Farers's four nomad origins.

- Expanded on the different outcomes you can wind up with as a "normal" lost colony.
- Finally implemented proper first contact dialogue for Remnants, lost colonies, refugees, etc.

Added compatibility with @☭ Red-Eyed_Fairace's Celestial Remnants origin.

Gestalt Consciousness empires with Remnants will no longer get the new functionality for that origin. This is temporary; I intend to give them a proper event chain like the normal empires.

- Updated to 2.6.
- Contested Homeworld is now an origin rather than a civic.
- Added a new origin: Interstellar Exiles.
- Wanderlust has been replaced by a new civic: Vengeful Refugees, which requires the Interstellar Exiles origin.
- See the wiki for more details.
