Merge branch 'development' of https://gitlab.com/marcel.schwarz/software-projekt-2 into 35-datenubertragung-zwischen-spielern

* 'development' of https://gitlab.com/marcel.schwarz/software-projekt-2:
  add Label to EntityManager and implement Labels to SettingsScene
  add LabelEntity, LabelNode and Labelcomponent - ability to customize and add a Label with animation
  add sharedInstance, small cleanup Code
  add button to SettingsScene for Background Movement
  forgot return type in func getVolume
  add button on-off to settingsScene
  fix multiple calls from startMenuMusic with static Bool, stop music when enter Game
  add SettingsScene with background and music also boolean query for multiple audioplayer start
  add backgroundMusic for MenuScene with SoundManager for futher Sound-Management - music with commercial use
