Update 0.7.1.1

• Added an information screen about current events and specials in-game when launching the game, and added a banner to the Container purchase screen, which opens the Premium Shop page dedicated to the Vive la France event.
• Fixed an error causing islands and landscape objects to disappear in battle/Port in some situations.
• Fixed guns elevation angles for battleship Bretagne. She now has the ability to fire both HE and AP at the distance specified in the ship's characteristics; before this, only the HE shells could be fired at that distance.
