rhino-ircd-0.2.0 released

After months of work, finally a new version. Most new features in this version:

* New module API
* Callback hooking API
* Event API
* New server root layout, with mods-enabled/ and mods-available
* Much more code is now implemented in a module, such as m_flood, m_stats and all user/channel modes

Unfortunately server to server links are not yet working, but is planned for the next release.
