Project Overhaul

[Rune580]

This will be used to track an overhaul of the UI along with some new features.

• Fix inconsistencies of the different UI elements. (Alignments, style differences, UX, etc)
  • Improve InputField UX
  • Replace the terrible category headers with a sidebar
  • Inline option description
  • Adjustable option sizes
• Replace all "runtime prefabs" with Unity prefabs
  • ChoicePrefab
    - Replaced with ModSettingsButton, Enum DropDown.prefab
  • GenericButtonPrefab
    - Replaced with ModSettingsButton, Button.prefab
  • KeyBindPrefab
    - Replaced with ModSettingsButton, KeyBind.prefab
  • CheckBoxPrefab (Used for retrieving checkbox sprite)
    - Checkbox sprites are now resolved as asset references instead of at runtime
  • ModOptionsPanelPrefab
• Proper navigation support
• Additional Option Types (Enum Flags, Int Step Slider, etc)
• Auto generate UI for all BepInEx Configs

Unlikely to happen without contributions:

• Full controller support (I'm not touching the obfuscated mess of Rewired, you can't make me)
