BUG - forbiddenSignStrings don't work.

[wolfebersahd]

Describe the bug Using forbiddenSignStrings on craft don't prohibit the piloting of the craft when a sign with that string is detected on the craft.

To Reproduce Steps to reproduce the behavior:

1. Have a craft with forbiddenSignStrings Example

forbiddenSignStrings:
  - "Dinghy"
  - "Cog"
  - "Corvette"

2. Restart the server
3. Place a sign with one of the forbidden strings on the craft
4. Pilot the craft

Results: The craft is piloted even though a forbidden sign string is present on the craft.

Expected behavior Piloting the craft should fail due to the forbidden sign string being part of the craft.
