Enhance PlayingCameraController #3
Description
Expand the camera's functionality on the pitch axis. Currently, the player can not look directly up, because the camera is always facings the player's structure. After the player has reached the min pitch (the lowest position), the camera should start rotating upwards without any more position change. This change is independent of the rest of the game, therefore it is a good issue for new contributors.
This change shouldn't affect the yaw and zoom functionalities end-result wise. Zoom might become a deprecated name after this change: it should (and still does) determine the camera's distance from the structure.
