Mars 1.50

[gkapulis]

• Fix: AI gets upset where it starts a colonization goal where the system already has colonized planets by someone else.
• Fix: Do not create radiating suns if the first planet is habitable.
• Fix: Do not select closest volcanic planets to radiating suns as a potential for orbit shift change event (making it habitable).
• Fix: Building list and troop list are deleted from a planet if it was a habitable volcanic and transformed to barren/desert - cause strange issues with the planet.
• Fix: remove queued building if they cannot be placed on the designated tile anymore.
• Fix: Colony screen stuck and may crash if pressing arrows to move between colonies if all colonists are die when the colony screen is opened.
• Balance: Reduce env change chance.
• Code: Protect PlanetGridSquare Habitable.
• Code: formatting change in Planet_EvaluateBuildings.cs
