High-level client API

by Nicoo for Tox

Design and implement a high level library (HLAPI) based on tox4j targeting the JVM. The idea here is to create a layer of logic between the low level API and the concrete client implementation. It should handle all the aspects of Tox that a client should support, including buddy lists, user informations, file transfers and chat logs. It should be platform-independent (no direct file I/O, for instance), run on the JVM and be easily useable from Java.
