Group-Office 4.0 beta almost ready

We've been working very hard on Group-Office 4.0 in the past year. We're almost ready to release the first beta version!

The most important changes in 4.0 are under the hood. We completely rewrote the PHP framework using the Model View Controller approach. On the interface it may seem like there are not so many changes but under the hood there's a shiny new engine! This get's us ready for the future and development will go much quicker. It will enable us to create a mobile interface for example. It's also a much more organized and more secure framework. At the moment extensive security testing is being performed by Cigitel.

Here's the list of changes in 4.0:

- Complete new MVC PHP framework
