Moved ini-file based config-classes from Engine to Sample Game project. Engine is now free of both Nini reference and the ini file itself. The actual game show now do what ever it wants (ie . reading from the ini file) supply parameters to EngineConfig.
Moved EngineConfiguration class to Core/Config and renamed as EngineConfig. Also added AudioConfig and GraphicsConfig classes.
Renamed Config.cs as SettingsReader.cs.
AssetManager is no more singleton and now instead referenced by Game.Services.GetService() request (issue #43).
ChunkStorage and InputManager are no more singletons now.
