2.0.0 Released

Version 2.0.0 has been released. Here's the changes:

Major updates:

* Went into a plugin architecture. Plugins are now stored in $(libdir)/libcdorganizer, and are loaded at run-time by the factory. This has changed the API significantly in a way that is not backwards-compatible, so instead of a 1.1.0 release, you get a 2.0.0 release.

* Windows support has not yet been written for this version. It will take some time to sit back and think of how plugins work in the Windows world and just how to integrate that into this project seamlessly.

Minor updates:

* Changed the error reporting to use the standard error_on_line rather than a custom cerr hack-job.
