Mod: Nation : Machaka Spider Cult

[Twan]

My first test being finished I've made the following changes :

- made the grey spiders better (13 def instead of 7, catching a running little spider isn't easy ; they remain crappy against missiles and ae spells)
- suppressed the air random on anansais to reduce the number of cross path items they can forge (and make them a little less powerful, mistformed spiders with fire shield and invulnerability in addition to a bless and eventually water/nature buffs were a little too good)
- kings now cost 750 gold but 300 ressources, to represent the ceremonies for their crowning which paralyze the nation ; I've also changed their picks, giving them nature 2 instead of the 50% random and 1 of their earth levels (note : the display of remaining ressources is buggy when you give a so huge res cost to a commander, but the creation works properly)
- added the griot as a new commander recruitable everywhere. Griots are storytellers using some illusion cantrips to illustrate their sagas. They have a standard capacity and air 1 (+10% of +1 air/nature). They also have a research bonus in sloth dominion like a philosopher

The new cost of the kings coupled with the griot bonus gives an interesting strategic choice to the nation. Without production in most cases to recruit a king will mean recruiting no other capitol only mage during 2/3 turns. Without sloth, griots are not better than witch doctors for research and have weaker magic for the same price (but may still be useful mages as they are the only ones with an access to air) ; with sloth 3 they become very good researchers for their price.

I've also added pretenders including a lich version of the machakan king and a legendary griot (rainbow human mage with dom 3 as many machakan believe that the First Storyteller has invented the world with his words).
