LGram16 e067522598 Initial commit: ROW Client source code 
Game client codebase including:
- CharacterActionControl: Character and creature management
- GlobalScript: Network, items, skills, quests, utilities
- RYLClient: Main client application with GUI and event handlers
- Engine: 3D rendering engine (RYLGL)
- MemoryManager: Custom memory allocation
- Library: Third-party dependencies (DirectX, boost, etc.)
- Tools: Development utilities
