New update (2.0.2)

Someone pointed out to me a glitch in the "Legacy Of The Lost Spell" demo. In particular, there was a separation in the rhinoceros and the trunk (made of 2 contiguous sprites) every now and then. I solved the problem by slightly changing the moment in which the sprites are set up (I updated the manual, in the chapter on scrolling and all the demos). Sorry for the frequent updates.
