Newfight code dedup

[luciensadi]

Overhaul and deduplication of combat code. Fixes several bugs, including:

• Activesoft canceling cpool was inconsistently applied
• Distance / penetrating strike did not always behave as expected
• Better logic around paralyzed and insensate characters, including cleaner messaging
• Fixed projections being immune to aggro
• Microfix to pluralization of ricocheting rounds
• Close Combat now applies the -1 power in defensive scenarios too (only matters if you win the clash and counterstrike)
• Nerve Strike tightened up to be more in line with the logic from the rest of the fight code
• Inanimate close combat message fix
