App refactoring almost done
- Created specific namespaces and folders for each app brick - Added proxy support using Starksoft's Biko Library - App bricks: Main, ChatBots, Crypto, Protocol, Proxy - Each class is now in its own file (Aes streams, chatbots) - Used "Bridge" design pattern for Crypto, Protocol, Proxy - Added back support for Minecraft 1.4.6 to 1.6.4 (MCC 1.6.2) - Need to fully re-test everything and fix bugs - To Fix : Server pinging is slow on SpigotMC - To Do : Add Minecraft 1.2.5 (MCC 1.3) and maybe 1.3 to 1.4.5
