On the right track!

• Entities' interfaces and abstract classes!
• Two types of plugins: World and Server
• New threading-model: a lot of things don't need to be thread-safe anymore
• ChunkGenerator API
• Better world access API
• Better command API
• Improved and fixed packets
• Various bug fixes
• More documentation
• Gradle wrapper

Third release: Commands, Packets, plugins dependencies and more!

• Add a command system, based on Apache Commons CLI
• Merge PacketsService and PacketsRegistry into PacketsManager
• Replace the Packet.handle() method by a separate PacketHandler, and allow multiple handlers per packet
• Add base packets (Status and Login packets in particular)
• Specify the dependencies format for plugins
• Use the "get" prefix for every getter
• Replace Chunk by ChunkSection (16x16x16 blocks) and ChunkColumn (16 sections aligned vertically)
• Remove block light level setters and getters. I will re-add them later, but it's not my priority for now.
• Other various improvements

Config update, and Gradle

• More classes were added in the utils package.
• The config package has been greatly modified. Configurations may now be corrected by a ConfigurationSpecification, which may be created by hand or based on an existing file. See the javadoc for more informations.
• The project also uses the Gradle build system !

First bugfix release

The API doesn't use any external library anymore.
The method Configuration.correct(ConfigurationSpecification) now works correctly: it replaces any invalid value, and delete or create entries when necessary.
