Modifier Assessment for Purge Decision Making

[edge-blade]

Plenty of bots decision making for purge is very rudimentary, or outright useless. Since the scripting engine doesn't seem to contain a way to decide if negative or positive buffs are attached, we should come up with a list of skills and their associated modifiers to look for so we can find the following, will definitely be annoying to maintain, but I don't see a better way to decide when to purge an ally for items like Witchbane, that has no secondary affects such as slow.

• Basic Dispel Buff
• Basic Dispel Debuff
• Strong Dispel Buff
• Strong Dispel Debuff

As a follow up item on this, we can rework Witchbane (item_heavy_blade) after this is done to assess allies properly and also have logic checks for enemy positive buffs.
