Agriculture modules are still a bit strange.

Issues

• Incorrectly show in tooltips of Mining Drills and Labs
• Appears that they are being inserted when Ctrl + Clicking (doesn't actually insert, correctly)
• Can be inserted into beacons when Bob's Module's setting Transmit Productivity is enabled (BUG)
• Helpers such as Helmod and YAFC have no way of knowing that mining drills and labs shouldn't accept Agriculture modules

Suggested fixes

• Remove control stage module insertion checks
• Disallow pollution in:
  • Labs
• Disallow productivity in:
  • Mining drills
• Either disable Bob's Modules setting to allow productivity in beacons. Or if it is enabled, disallow pollution in beacons
• Remove pollution effect from productivity and god modules (Bob's modules)

Side effects

• Green, Pollution Cleaning, and Pollution Producing modules will no longer be usable in Labs
• If Bob's Module's setting Transmit Productivity is enabled, then Green, Pollution Cleaning, and Pollution Producing modules will no longer be usable in beacons
