Clean setup file, create launch script

- Setup file: 'entry_point' is used in stead of non-existent
  'bin/hackertray' for scripts
- hackertray package init file
  - does not check if it is called as a script (which should not happen)
  - main() code is now replaced in HackerNewsApp.run()
  - main() instantiates the app and calls run() on it (previous roles
    grouped)
