* God, that's a lot of hardcoding

* Fixed belt2 smartequip and cleaned up

* Continued clean up

* No scope creep!

* Replaced belt1 for upstream default belt

* Moved CP14OpenSkillMenu to CP14ContentContexts

* Changed naming of belt1 textures to just belt

* Updated new belt1 refrences

* I forgot to edit the RSI meta
