Enemy AI 2 - Difficulty levels

[DouglasOrr]

Either/and:

• Agent takes better/worse decisions
• Enemy receives resource boost/penalty

TODO:

• Wire up resource bonus/penalty
• Defend when being invaded
• "Rebase" when stuck
• Difficulty modifies combat behaviour

[DouglasOrr]

Rebase when stuck idea:
When retreating, count down a 'patience' timer (maybe 30s). When the patience timer elapses, enter flee (causing move to the home moon, skipping normal behaviour) until the leader is within orbit.

Defend when invaded idea:
When there are any enemies in a radius of home & the leader is not, move to the home moon.

This requires a new hierarchy mode (precedence between plan and action), which can be normal or flee.
