[TASK] Moved the project to namespaces.

[TASK] Removed all the protocol handlers. [TASK] Clients are no longer part of the SocketFramework itself. [TASK] The Framework provides an "interface" to external clients - the ClientDispatcher. [TASK] Added the Core package and added a better ClassLoader. [TASK] Created a bootstrap module to include in other projects. [TASK] Cleaned up comments, reformatted them.
