Dialog subtitles

[JaXt0r]

TODOs

• Subtitles for NPCs should be visible above their head and are rotated towards us (As we can't move in the future it will be a fixed value when dialog starts)
• Subtitles for our hero
  • should be slightly below our view (golden cut or so)
  • They should have a delay when moving with us for convenience (you can reuse the Chapter switch screen logic - there's a movement delay implemented already) - HVRIntroduceChapter.cs
• Dialog settings can be altered on our MainMenu
• (Bonus) We can also read and write the subtitle setting from gothic.ini. The ini file is already read in our game. We just need to implement the save as well. - Please read+save the settings inside PlayerPrefsManager then

• Player locked in place during cutscene.
• Subtitles displayed for both NPC and Player (With the name of the 'talker' above message).
