Credits to mescon that showed me this bug in action in the first place, on the aerowalk-jump also 
included in this demo-pack.
I started fooling around a bit, and came up by myself with some other jumps that are possible with the 
kfjump(bug!).
I dont know, maybe some people already are aware of the bug and have seen it in action, but I know I
havent until just a couple of weeks ago, when mescon showed it to me.  
btw, demo 1-2 are recorded on the map cmt4, demo 3 on aerowalk, demo 4-5 on dm2 and demo 6 on cmt1.
If anyone of you comes up with another jump, please DO bother to upload them =B-)
