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.

- Changed thumbnail (for real this time).
- Mars is now size 15 instead of 13.

Fixed some typos.

Fixed thumbnail(?).

Fixed accidental re-upload.
