Bug fixed.
Bug info: Host and port were always overwritten with environment variables MYPROXY_SERVER and MYPROXY_SERVER_PORT when they had been obtained through openid (--openid option) or through properties file .MyProxyLogon

Looks good to me. Tested on IPSL test fed.

1. The host and port configured by (--openid, --oid) command never will be overwritten. Unless you used the --pshost and --psport commands.

2.  The host and port configured by  .MyProxyLogon file never will be overwritten. Unless you used the --pshost and --psport commands.
