European Portuguese added TODAY!

First of all: Thanks to my mother who translated the game to European Portuguese from the English and the Brazilian Portuguese translation. She comes from Portugal so I always wanted to have a Portuguese translation of the game. Obrigado, mãe!

Also, my fiancee modified the Kenney Future Font to improve the readability (on the letters K and X to distinguish them better from the H and from each other). This change is subtle so it doesn't affect the style of the Font too much. This should help in all languages but especially in German.
