Feature parity for games

[Laupetin]

To avoid confusion for users, supported games should at least have feature parity for assets, that all of them support.
To achieve that, more loading and dumping code should be either shared or generated to allow for minimal code duplication.

The following assets are currently implemented for one game but not others:

• PhysPreset
  • Supported: IW3, IW4, IW5, T5, T6
  • Unsupported: T4
• (Addon)MapEnts
  • Dumps: IW3, T4, T6
  • Unsupported: IW4, IW5, T5
• Menus
  • Supported: IW4, IW5
  • Unsupported: IW3, T4, T5, T6
• Weapons
  • Supported: IW3, IW4, IW5, T5, T6
  • Unsupported: T4
• Image
  • Loads DDS: IW3
  • Loads IWI: IW5, T6
  • Unsupported: IW4, T5
• Techset
  • Supported: IW3, IW4, T5, T6
  • Unsupported: T4, IW5
• Tracer
  • Supported: IW4 (Only dump), T6
  • Unsupported: IW5
