Add roguelike tutorial implementation files

Implement Parts 0-2 of the classic roguelike tutorial adapted for McRogueFace:
- Part 0: Basic grid setup and tile rendering
- Part 1: Drawing '@' symbol and basic movement
- Part 1b: Variant with sprite-based player
- Part 2: Entity system and NPC implementation with three movement variants:
  - part_2.py: Standard implementation
  - part_2-naive.py: Naive movement approach
  - part_2-onemovequeued.py: Queued movement system

Includes tutorial assets:
- tutorial2.png: Tileset for dungeon tiles
- tutorial_hero.png: Player sprite sheet

These examples demonstrate McRogueFace's capabilities for traditional roguelike development.

+McRogueFace Tutorial - Part 0: Introduction to Scene, Texture, and Grid
+
+This tutorial introduces the basic building blocks:
+- Scene: A container for UI elements and game state
+- Texture: Loading image assets for use in the game
+- Grid: A tilemap component for rendering tile-based worlds
