This reverts commit 33602998a3d1a65b67bc409e51d38acf1c95843d.
changed argo's trigger shape for various zombies and melee human.  It is more of a skewed square now.  This fixes some targeting bugs.  Essentially the zombie will have less of a chance of targeting a barricade, which is behind the human, before attacking the human
JumpOver.js revised so the scout zombie actually leaves the trigger of a human.  Otherwise, the human keeps shooting the scout no matter how far it gets
