Revise and/or automate tracking defeating bosses without taking damage

[CPColin]

Combining two ideas we've been chatting about:

• We should try to detect when the player defeats a boss without taking damage
• Tracker should make fun of the player when they're proud of defeating an easy boss without taking damage

I think we can manage the first one by making a list of boss rooms and monitoring the player's health for decreases while the player in in that room. We'd then also have a list of bosses that count as "easy" and don't automatically grant content for no-hit defeats:

• Ball-and-chain soldier
• Armos Knights
• Bomb Torizo

If we want to be real fancy, I could see some other bosses we talked about being dependent on your gear or other things that have happened. Crocomire may not give content if you have the charged plasma. Lanmolas if you have the fire rod. Moldorm if you fall.
