• Set dynamic claimant faction ultimatum threshold, depending on the most likely strength of all joining subjects.
  
• Reworked call to arms and now really removed duplicate calls for one person.

Added "Claimant Faction cb" support, because I thought it was handled by a normal claim cb.
Now much less vassals will join.

• Removed dependency on the "war_on_actions.txt" file.
  
• Fixed bug for characters event decision on religious wars.
  
• Increased chance of vassals not joining as a defender, if the war would only result in a new liege for them.

Added game rule VtA - Affected

• Title Loss & Vassalization (default): All realm rulers that would lose a title or would get a new direct liege are called to war.
  
• Title Loss: All realm rulers that would lose a title are called to war.

• Fixed issue, where vassals with land outside the targeted title would lose the land inside, but not join as a defender.
  
• Fixed bug, where two wars declared at the same time would only trigger the event for one war (Ex. 1066 wars of Harlod II against Normandy and Norway).
  
• Fixed a bug, where the top liege would be called into a war against an indirect subject with a direct one.

• Fixed a bug for multiple event calls for one person.
  
• Duchy casus belli and ducal conquest cb AI reasoning improved, if they would end up becoming a vassal of the attacker (before: would always join defender).
  
• Logic for invasion casus belli added and improved as well (before: would always join defender).
