Version update for 5.2

• Malakai Malakaisson favours all Slayer regiments of renown with a Missile resistance buff, representing his unusual ranged/Slayer combination of personality traits.
  
• Tamurkhan the Maggot Lord favours the Rotting Riders (Rot Knights) with a Missile resistance buff as well.

• Mahaduvha, the Deva of Blood favours The Marquis of Masochism (Keeper of Secrets) with a special buff that inducts them into her cult (Poljanan's Sect of Akhalee)

• Kugath Plaguefather's extra Nurgling RoR unit is now properly available (thank you, Sithdude, for the report)

• Epidemius favours the Festering Stooges (Plaguebearers).
  
• Kugath Plaguefather has been changed. He still favours the Frolickers Bubonic (Nurglings), but lost the Festering Stooges to the more closely linked Epidemius. Since the Frolickers are fairly weak, he has been allowed to have two Favoured Regiments, and the second has been changed to Uncle Furuncle (Great Unclean One), as Kugath is a Great Unclean One himself.
  
• Elspeth von Draken favours Grundel's Defenders (Spearmen), as they are a Nuln-based regiment.
  
  Malakai and Tamurkhan are still pending.
