Refactor remaining classes to use WebOfTrustInterface.WOT_NAME instead of WebOfTrust.WOT_NAME:
- Most of the previous commits all were classes which I had searched by hand for any usages of class WebOfTrust. I did this by hand because I want the classes (Own)Identity/Trust/Score/IntroductionPuzzle/OwnIntroductionPuzzle to be copy-pasteable into other plugins. The remaining classes which are changed by this commit don't have to be copy-pasteable and therefore were adapted by the Eclipse "Move" feature.
