Implement comprehensive rate limiting system and item spawn configuration

Browse source 
Major Features Added:
- Complete token bucket rate limiting for IRC commands and web interface
- Per-user rate tracking with category-based limits (Basic, Gameplay, Management, Admin, Web)
- Admin commands for rate limit management (\!rate_stats, \!rate_user, \!rate_unban, \!rate_reset)
- Automatic violation tracking and temporary bans with cleanup
- Global item spawn multiplier system with 75% spawn rate reduction
- Central admin configuration system (config.py)
- One-command bot startup script (start_petbot.sh)

Rate Limiting:
- Token bucket algorithm with burst capacity and refill rates
- Category limits: Basic (20/min), Gameplay (10/min), Management (5/min), Web (60/min)
- Graceful violation handling with user-friendly error messages
- Admin exemption and override capabilities
- Background cleanup of old violations and expired bans

Item Spawn System:
- Added global_spawn_multiplier to config/items.json for easy adjustment
- Reduced all individual spawn rates by 75% (multiplied by 0.25)
- Admins can fine-tune both global multiplier and individual item rates
- Game engine integration applies multiplier to all spawn calculations

Infrastructure:
- Single admin user configuration in config.py
- Enhanced startup script with dependency management and verification
- Updated documentation and help system with rate limiting guide
- Comprehensive test suite for rate limiting functionality

Security:
- Rate limiting protects against command spam and abuse
- IP-based tracking for web interface requests
- Proper error handling and status codes (429 for rate limits)
