UI update for controlls — Rise of the Village Hero Steam update #290829

Hello, This change should not affect the game or your save; it simply corrects the quick save/load keys to the correct ones in UI controls, which are F2/F3, instead of the mistaken F2/F4. This was a typo; the code for quick load keys has always been F3, so nothing has changed in that regard. Additionally, descriptions for zooming in/out with the mouse wheel and rotating the camera with the right mouse button have been added to the controls UI. I hope this clarification helps. See you at the next update. Best regards, Silviu
