optionsmodel cleanup

- cleanup optionsmodel before adding new proxy options
- place SOCKS version stuff below proxy port (IP, Port, SOCKS version)
- simplyfy some parts of the code (e.g. don't check IP and port, as this
  is done in optionsdialog anyway, remove unneeded {} in switch/case)
- small cosmetic changes in the header for better readability
