Added game explorer for actually searching games.

I wrote the game explorer, which communicates with the database and adds games.
There are some errors in there i hope you can fix them, but my head feels
like rotten wood, i can't quite think...

i will extend this with the feature to add a game, but not today... you can
cheat a bit tomorrow and add some random games to the database, to show him this
tomorrow, and then i will add the real feature...
