AI improvement - hero roles

[GoogleCodeExporter]

Observing the AI movements thanks to the new online open mode, I have come to 
the conclusion that AI treats all his heroes equally.
This is not the best way to manage your kingdom.

AI should use his starting hero as a scout/gatherer, exploring the map and 
collecting free resources and mines. Most important skills for him are: 
logistics, pathfinding, scouting. More is even not necessary.

The second hero will be trained as the main force, putting more EXP in it and 
giving him/her better armies. Important fights will be preferred to be done 
with the main hero.

The third hero is a supplier for the main hero: his main role is to bring 
reinforcements to the main hero(es) - the supplier has less armies, and has 
less EXP (most important skills to consider: logistics, pathfinding, scouting, 
wisdom, earth magic (town portal), diplomacy)

Subtypes of the main hero:
"Bruiser":
sec. skills: Offence, armorer, luck, leadership, ballistics, logistics, 
pathfinding, resistance
creatures: any, dominantly the most XP, better attack/defence. Speed is not 
important.
strategy: conquer, gather army, and dominate (defend) conquered land.
preferred hero race: barbarian/knight/necromancer

"Blitzkrieg" 
sec. skills: logistics, pathfinding, wisdom, earth magic, air magic, fire 
magic, sorcery
creatures: ultimately - dragons. In general, tough AND FAST creatures. 
Flyers/shooters.
strategy: ignore minor targets on map, avoid fighting main enemy heroes far 
from enemy capital, take major enemy castles, important mines (gold and 
relevant resource - i.e. sulphur is fighting vs. warlock). Ultimate tactics - 
dragons+expert armageddon, one strong fast troop+antimagic, and mass 
destructive spell next turn. Town portal for transportation.
preferred race: warlock, wizard, sorceress
artifacts of most importance: +speed, +speed for troops, +magic effect

strategies for secondary hero types:
"thief" 
this is the strategy for the "scout" when exploring enemy land - take most 
important resources/mines, free artifacts. (gold/most relevant res. types for 
enemy/most relevant res types for himself)
preferred tactics: avoid enemy contact, always rearrange troops in many squads 
("1, 1, 1, 1, 1, THE_REST"), if forced to fight - hit with a destructive spell, 
and run. Give gathered artifacts to main heroes.

"attache" 
this strategy is used by a "supplier" when accompanying a main hero in the 
enemy land. 
activities: Gather resources (if accompanied, main hero will ignore non-EXP 
resources, and take only chests, and artifacts). Give gathered artifacts (if 
any) to main hero. Defend conquered castles instead of the main hero, to let 
him move on.
