Tribix 2.3.0 released

I'm pleased to announce that Tribix 2.3.0 is released.

Some main changes follow:

1. Support BIRT 2.2/2.3 series.
2. New layout mode support, which effectively reduces the count of columns generated and provides better look.
3. Enhanced image formats support, now support any image format that recognized by AWT.
4. Support hyperlinks for text element.
5. Update POI dependency to 3.1.0 Final.
