Most important changes since 0.6.0 final:
* Now compact mode resizes the window, instead of leaving black borders.
* Added an option in Preferences->Interface which allows the user to select
his/her preferred GUI. This way it's easier to use the mini GUI, for those
who prefer a simpler interface with few buttons.
* One more fix for Qt 4.4. The option FAQ in the Help menu didn't work.
* (Windows) Fix: zoom didn't work well (black blocks appeared) if using
* Added the Catalan translation.
