issues on system_advanced_admin.php
1) spews some debugging out.
WebGUIProto = https
2) changing TCP port for webGUI doesn't work
3) max processes changes aren't saved
4) SSH settings aren't those from the config, and changing them doesn't work.
5) serial/console changes don't work
seems most of the fields here outside HTTP/HTTPS selection fixed in #4970 don't work, check them all.
