Moved the management of cameras into the Map class. The View class no longer exists since it now serves no purpose. The engine class itself holds the renderers and these get passed to each map that is loaded and then passed to each camera on each map. This change makes it possible for multiple maps to be loaded at the same time with the same camera id without a name clash. fixes[t:342]
