More fixes! (And some other stuff)

Another update in the same day! I'm so quirky.

-Improved the graphics of a tile.

-Added a `leniency` mechanic to action commands where getting perfects are easier the more times you fail.

-Getting a semi-perfect on smith's gun minigame is now easier.

-The 'parry stance' skill now caps at 15 TP gain, instead of 12.

-The 'shinobi assassination` skill now uses the slash and nix elements.

-Fixed the cutscene of Adam waking up at the amino woods inn.
