Text scroll change — Word Attack Steam update #259003

Changed the way text in information panels is held on screen. All the historical text should now be visible where as before it was a rolling list of the latest x lines (the more memory your system had, the more lines it kept). Scrolling down now removes all the old text above from the scene graph so that it will no longer need considering when drawing frames. Also in this build: Changed the number of stars generated when finding words in the Slide game, more so if you have set a low amount of memory for graphics.
