SampleMan 3: Asteroids - 1.1

not like classical Asteroids game should work with Python 2.5

- fixed: now killing two or more asteroids at a time is really better than one - fixed: i had a float division error when mouse was on player's center - changed menu: added highscore table, sound control, "settings" submenu - highscore table is displayed after death, and can be closed only after some time - settings are now saved in a file - added FPS label, if your FPS is below 24, it is recommended to turn off clouds - as an experiment: a little part of the code moved to C++ - added floating text when you gain score killing an asteroid
