Desirability change after loading game

[medea_fleecestealer]

Not a bug, desirability was changed a bit in the last patch.

@Zantai

• Increased Desirability requirements for Shelter upgrades. This change is NOT retroactive for existing shelters and only affects newly constructed/upgraded shelters but the Shelter window does reflect the new values.
• Slightly reduced the desirability radius of various small to medium size decorations and entertainment buildings. Overall, desirability radii are still considerably higher than v0.9.2.
