[rework] make Odinnstru more extremist

[CyberNord]

The faith should be an extremely violent and zealous faith.

• massive negative opinion against nonbelievers
• more emphasis on war and executing heretics
• make character traits like cynical a sin
• follower of this faith should be able to get armies rather easy but lack in defense or economy.
• raiding should be a major part, but make a mali on raiding brothers in faith.
• make this faith a crisis that will be weaker as the game goes on (low innovations, development, economy, etc. )
• it should be natural that this faith "die out" around 1066...
