Resource no.4: differing between thumbnails and portraits
Resource no.5: default portrait and default thumbnail
Resource no.6: extra writer list (probably never use)
quick fix: thumbnail folder was called thumbnail folder (note the "b")
Improve <5> showing portraits Improve.

- Now displaying thumbnails (38 x 60) instead of portraits (110 x 170)
- Displaying a better default thumb
- Reordering elements in panel.
Refactor: improving the class hierarchy in the gameLogic.staff package.

- Employee (abstract) Everybody has a name (String), overall (int), salary (double)
- StaffMember (abstract) the 5 main characters of the game: Director, ProductionDir, ScriptWriter, Post and Hero has thumbnails and portraits
- Director extends StaffMember (extends Employee)
