Tradesecrets in professions

[Nando Neck]

Currently tradesecrets cannot be added to a profession.

This needs to be added, because we need it for Waffenschmied der Tapo-Tikaute

Name: Gumijok verarbeiten

[Bernhard Jung]

Fixed in commit dd92826 i

It is now possible to define a trade secret variant that is based on actual trade secret:

{ 
  "type": "tradesecret", 
  "tradesecret": "gumijokverarbeiten" 
}
