 - T-bots: fetch bomb backpack when it has been droppen.
 - T-bots: plant the bomb.
 - T-bots: roam the planted bomb.
 - CT-bots: random buy defusal kit.
 - CT-bots: defuse bomb.

 - Small waypoint adjustments for `de_dust2` which enables bots to
   successfully jump on the big boxes to B, and they jump more easy over the
   ridge from T spawn to B.
