Fix support for ClothConfig/ModMenu

[SpencerBurgess]

The reasoning for this PR:

• The ModMenu for Simple HUD Utilities no longer appears after the latest release of V 2.5.0
• Users can't use ModMenu/CothConfig to edit their Simple Hud Util config

Changes addressed in this PR:

1. AutoConfig is now maintained and part of the ClothConfig project, all dependencies on the old package are updated
2. Incremented version number to 2.5.1 as this is a hotfix and contains no new features

You can find mentioned where the AutoConfig dependency was taken over by ClothConfig here:
