Title:
  SIGSEGV crash on CControl::CheckTreeCollisions when no trees in level

Bug description:
  Hello everybody,
  I found a bug when I was playing "Who Says Penguins Can't Fly?". If you start this level as first, ETR will crash. SIGSEGV is fired because TCollidable *trees is NULL in levels with no trees and in CControl::CheckTreeCollisions(...) is that variable indexed.
  Patch is in attachments.
  Please correct me if CControl::CheckTreeCollisions(...) quit isn't ok.
  Thank you,
  Jakub Vanek
