Fix pid handling in create_win_return_wid

- Simplify logic
- Properly handle both the case where a "special" program needs to be
  started and where it has already been started (did not actually work
  before because the first pgrep somehow stopped the second from working
  correctly)
- Add support for "chromium-browser"

Closes #20.
