Added StartLevel component to SplashScreen and Levels scenes. This way the activation of the player an other components is handled uniformly. Other fixes
Changed the way the fadeable component from camera was obtained. This avoids a runtime warning casting message
Pausing game behavior now enables/disables the MonoBehaviour components instead of deactivating the gameobject. This way the rendering still happens, but no updates are invoked
Solved runtime message "!IsActive () !m_RunInEditMode"
