remove refs to /etc/pivpn/setupVars in selfcheck and debug scripts

tidy indenting
  on install, check if symlink already exists before making one to avoid error
  uninstall indicates which vpns are available for uninstall
  selfcheck checks both protocols if both present
  install - additional text in reconfigure saying 2nd protocol can be added
  change to use pivpn ovpn instaed of pivpn opv when dual protocols exist
