Updates since RC2

Development has been busy since the last release with no small thanks to all the great feedback we have received. We now have a simple translation system for plugins (which the filters and "hello world" plugins are using), database storage support for contacts, a new theme, better folder list handling, and several bug fixes. We hope to have another release before the end of the year so check back soon. Thanks to everyone who has provided bug reports and testing, we appreciate your support.
