Minor bug fixes and balancing update

Buffed player accuracy as missing was unreasonably common.
Made rats poison less for more attack power.
Added loot to the human castle pot and the crossing towers as well as changed some text in the demon castle.

Discovered why NG+ caused a game over for some players and fixed it. 
Shrunk some maps by a few tiles and made a slight redesign to the demon castle's first floor.

Introduced the ability to change your name.
Minor Anglish and Japanese translation to the story / overworld text.
Made the crossing towers not weird to quickly traverse.

To do:
Translate story and database into Japanese or Anglish, the rest can come later.
