New homepage and more game subjects

Helpful Games has a new homepage which is much less static. Now you will find toplists, events and comments right at the homepage. We have also taken the opportunity to create more subjects in accordance to the subjects in the schools. This has also meant that some games have been moved to new subjects (formerly game categories). Some of the games that have been moved are the games about the clock, which now may be found under mathematics, and the calendar games, which now resides under English.
