ltris: Update to 1.0.20

Changelog:
After watching CTWC (which is awesome) and starting to play tetris
again myself I finally took the time to add wide screen support to
LTris (my monitor gave me severe seizures in fullscreen...) by
using a shadow surface. It is just software scaling but hey at
least it is playable again in fullscreen.

As with Barrage: SDL will return bad mouse positions if switching
window -> fullscreen. You'll need to switch and then restart the
game. Nothing I can do about it, sorry.
