New Skill: Knowledge - Martial - Int

In addition to the uses outlined in the original Path of War expansion for Pathfinder, Knowledge (Martial) can also be used for the following intel:
Identifying Class: A high enough knowledge (martial) roll can inform a character about an enemy's class. The DC for this is 10 + the enemy's CR or HD, whichever is higher.
Identfying Feat: A high enough knowledge (martial) roll can inform a character about a feat that was just used. The DC for this is 15 + the enemy's CR or HD, whichever is higher.
Predicting Attack Patterns: Knowledge (martial) can also be used to determine if there is a strategic pattern of attack, either in a single combat by a single enemy, or by an entire army led by multiple generals. The former will generally yield more specific information than the latter.
