[1.2.319] [ENG] Adventurer skill revamps

I see the same thing for Captains/Corsairs as well:

Rapid Fire > Battleship Cannon

Therefore,

1. Costlier Method: Rapid Fire wastes ammunition but kills enemies faster.

2. Cheaper Method: Battleship Cannon saves mesos, but kills enemies slower. (Cannon deals more damagw per bullet, right?)

That's the stupidest thing I've ever heard. We'd just buy more ammo. I only use 7 slots at the moment for bullets, I could easily spare more.

Cannon should be significantly more powerful than RF, no questions asked.
