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
