Make dhcrelay GUI be simple and easy to use by collapsing the interface tabs to a multiselect control. Remove proxydhcp option because it is broken and is not trivial to make it usable(if user request for it a reconsideration will be made). Allow multiple server ips on the server input box separated by commas. Also on the interface list do not show interfaces without an ip because dhcrelay will not be happy with them. Upgrade code is also included in this commit.
