Fast Config API

Rewritten the whole API (v2, beta)

• Added new FastConfig annotation
• Added new Loader annotation
• Now all configs are loaded dynamically and automatically
• Now configs can be loaded through URLs
• Now configs are managed with both sync and async methods
• Drastically simplified the whole API:
  • FastConfig annotation automatically creates configs
  • Loader annotation defines a specific loader to use to write/read configs
  • Serializers are used to serialize and deserialize classes / strings
  • Removed config registration at startup (now all configs are automatically registered)
  • Added the FastConfigs class to access all the configs
  • Added specific-side configs
  • Added config subdirectories
  • Added loader silently failure
  • Added loader specific deserializer
