Patch notes

Changes

• You can now duck twice in the air. Scout double jumps reset the in-air jump counts
• Added "tf_clamp_airducks" convar, set to 1 by default
  • Setting it to 0 will remove all constraints on ducking while in the air. Useful for servers running RJ challenge maps

Bug fixes

• Increased the jump velocity to account for the tuned bounding box sizes. Jump height should now match the prior-to-last-update heights
