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- Wanderlust has been replaced by a new civic: Vengeful Refugees, which requires the Interstellar Exiles origin.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.

More minor bugfixing.

Minor bugfixing, slight improvements to the Vigil system.

- Minor bugfixing.
- Bekonda and Oldara are now (cold) Barren Worlds (instead of Broken and Frozen, respectively).

- The Vigil system is now a Brown Dwarf rather than a Black Hole.
- New Xarmir is now a Tundra World rather than a Tomb World.
- Removed the wormhole connecting Vigil to Xir'a.
- Renamed the planets of Vigil and Xir'a to better match their species owning them.

Numerous minor localisation improvements.

Empires with a Distant Origin trait will no longer have their climate preference changed if they are also Life-Seeded.

Disabled New Xarmir spawning as a Radiotrophic World; this will return when I get get it to work more reliably.
