Something with either minecraft or EMF updating caused the trails to be significantly shorter than intended, so this update nearly doubles the size of the trails to compensate.
IF THE TRAILS ARE TOO LONG WITH THIS VERSION, USE VERSION 1.3 INSTEAD. THE SIZE OF THE TRAILS ARE THE ONLY THING THAT CHANGED.
No longer needs player jem, added respackopts settings
Made the rotation of the contrail more closely match the rotation of the camera (both for f5 and for looking at other players). still not perfect but this is the closest I think I am going to get
Made the contrails be one plane instead of a cross (looks a bit better)
has slight camera tracking but not perfect
Initial release
