Implement comprehensive IGDB integration for real-time game information

## Major Features Added

- **Enhanced igdblib.py**:
  * Added search_games() method with fuzzy game search
  * Added get_game_details() for comprehensive game information
  * Added AI-friendly data formatting with _format_game_for_ai()
  * Added OpenAI function definitions via get_openai_functions()

- **OpenAI Function Calling Integration**:
  * Modified OpenAIResponder to support function calling
  * Added IGDB function execution with _execute_igdb_function()
  * Backward compatible - gracefully falls back if IGDB unavailable
  * Auto-detects gaming queries and fetches real-time data

- **Configuration & Setup**:
  * Added IGDB configuration options to config.toml
  * Updated system prompt to inform AI of gaming capabilities
  * Added comprehensive IGDB_SETUP.md documentation
  * Graceful initialization with proper error handling

## Technical Implementation

- **Function Calling**: Uses OpenAI's tools/function calling API
- **Smart Game Search**: Includes ratings, platforms, developers, genres
- **Error Handling**: Robust fallbacks and logging
- **Data Formatting**: Optimized for AI comprehension and user presentation
- **Rate Limiting**: Respects IGDB API limits

## Usage

Users can now ask natural gaming questions:
- "Tell me about Elden Ring"
- "What are good RPG games from 2023?"
- "Is Cyberpunk 2077 on PlayStation?"

The AI automatically detects gaming queries, calls IGDB API, and presents
accurate, real-time game information seamlessly.

+# IGDB Integration Setup Guide
+
+The bot now supports real-time video game information through IGDB (Internet Game Database) API integration. This allows the AI to provide accurate, up-to-date information about games when users ask gaming-related questions.
+
+## Features
+
+- **Game Search**: Find games by name with fuzzy matching
+- **Game Details**: Get comprehensive information including ratings, platforms, developers, genres, and summaries
+- **AI Integration**: Seamless function calling - the AI automatically decides when to fetch game information
+- **Smart Formatting**: Game data is formatted in a user-friendly way for the AI to present
+
+## Setup Instructions
+
+### 1. Get IGDB API Credentials
+
+1. Go to [Twitch Developer Console](https://dev.twitch.tv/console)
+2. Create a new application:
+   - **Name**: Your bot name (e.g., "Fjerkroa Discord Bot")
+   - **OAuth Redirect URLs**: `http://localhost` (not used but required)
+   - **Category**: Select appropriate category
+3. Note down your **Client ID**
+4. Generate a **Client Secret**
+5. Get an access token using this curl command:
+   ```bash
+   curl -X POST 'https://id.twitch.tv/oauth2/token' \
+   -H 'Content-Type: application/x-www-form-urlencoded' \
+   -d 'client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=client_credentials'
+   ```
+6. Save the `access_token` from the response
+
+### 2. Configure the Bot
+
+Update your `config.toml` file:
+
+```toml
+# IGDB Configuration for game information
+igdb-client-id = "your_actual_client_id_here"
+igdb-access-token = "your_actual_access_token_here"
+enable-game-info = true
+```
+
+### 3. Update System Prompt (Optional)
+
+The system prompt has been updated to inform the AI about its gaming capabilities:
+
+```toml
+system = "You are a smart AI assistant with access to real-time video game information through IGDB. When users ask about games, game recommendations, release dates, platforms, or any gaming-related questions, you can search for accurate and up-to-date information."
+```
+
+## Usage Examples
+
+Once configured, users can ask gaming questions naturally:
+
+- "Tell me about Elden Ring"
+- "What are some good RPG games released in 2023?"
+- "Is Cyberpunk 2077 available on PlayStation?"
+- "Who developed The Witcher 3?"
+- "What's the rating of Baldur's Gate 3?"
+
+The AI will automatically:
+1. Detect gaming-related queries
+2. Call IGDB API functions to get real data
+3. Format and present the information naturally
+
+## Technical Details
+
+### Available Functions
+
+The integration provides two OpenAI functions:
+
+1. **search_games**
+   - Parameters: `query` (string), `limit` (optional integer, max 10)
+   - Returns: List of games matching the query
+
+2. **get_game_details** 
+   - Parameters: `game_id` (integer from search results)
+   - Returns: Detailed information about a specific game
+
+### Game Information Included
+
+- **Basic Info**: Name, summary, rating (critic and user)
+- **Release Info**: Release date/year
+- **Technical**: Platforms, developers, publishers  
+- **Classification**: Genres, themes, game modes
+- **Extended** (detailed view): Storyline, similar games, screenshots
+
+### Error Handling
+
+- Graceful degradation if IGDB is unavailable
+- Fallback to regular AI responses if API fails
+- Proper error logging for debugging
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"IGDB integration disabled"** in logs
+   - Check that `enable-game-info = true`
+   - Verify client ID and access token are set
+
+2. **Authentication errors**
+   - Regenerate access token (they expire)
+   - Verify client ID matches your Twitch app
+
+3. **No game results**  
+   - IGDB may not have the game in their database
+   - Try alternative spellings or official game names
+
+### Rate Limits
+
+- IGDB allows 4 requests per second
+- The integration includes automatic retry logic
+- Large queries are automatically limited to prevent timeouts
+
+## Disabling IGDB
+
+To disable IGDB integration:
+
+```toml
+enable-game-info = false
+```
+
+The bot will continue working normally without game information features.
