Climber bug

[Jorrit Tyberghein]

Well this is my first day using Pingus. So forgive me for being so 
verbose :-)
But I discovered another bug which is easily reproducable on my system.
I just start the headbang.xml level. Then I make convert a few pinguins
to Climbers and let them crawl outside the pit. Then I don't touch them
anymore. After a while they start climbing the big column on the right.
It appears that one in two times they climb this column on the wrong side
(i.e. they appear INSIDE the solid column instead of walking on the
surface).
