Split DecideAction into several specialized DecideAction functions

* Removes the need to constantly check for fCivilian, ARMED_VEHICLE, ENEMY_ROBOT etc inside DecideAction
* Move AI decision checks into their own functions, such as DecideActionRadioRedAlert
* Add new entry to ActionType. AI_ACTION_INVALID signals that no valid action was found when a function returns, or no valid action is possible
* Do a weighted random selection for choosing target under DecideActionBlackSoldier
