Weed Killer Fixes

Fixes bugs with weed killer:

• Fixed vain shrouds ignoring weed killer as of the v60 update. (Only applies to old save files, or YesFox)
• Fixed the broken cooldown for adding HP/turbo to the Cruiser, which caused most of your sprays to be wasted. You should consistently get results each spray now
• Fixed spray collision so it can detect vain shrouds that grow inside walls, terrain, under the ship, etc.
• Fixed lag spikes
  • When weeds get destroyed
  • When spraying the Cruiser
