What comes with JG by default

• The item stack count fix, as this is not a gameplay change, but purely a functional change.
• bFixDeathVoicelines enabled, as this fixes voice lines on death being cut off halfway through.
  

The other optional features are disabled by default because they alter the vanilla game and could be seen as
gameplay changes. The loading FPS tweak will lead to large loading time increases if set above 40.
