Battleship: Update ruleset and add one more

[FlyingWolFox]

New Game Mode
There's two rules to be implemented

• 1. Easy Rule:

  • 3 shots
  • Show which ship was hit in each shot

• New ship artwork for the hard rule

• 2. Hard Rule:

  • 3 consecutive shots (no display between each other)
  • Show how shots many hit, but not which, also displaying the what ship was hit. If one sunk, show the entire ship on display

Easy rule implemented. Now there's three consecutive shots. It's just a loop inside the input. Hard mode will need some new artwork. One for the "Shot here but the hard mode doesn't show me what", one for the hidroplane and maybe some changes of the actual ship design, since this need to show what ship the shoots hit. Working this right now
