No Hobbit menu in maint.pl

When you use maint.pl, there are no links back to the main Hobbit page, nor the menu overlay. So, when you enable/disable a host, the only way to get back to the main hobbit page is to click back several times.

Note: it's not a problem with bb-ack.sh, as the Hobbit menu remains overlay so you can easily click "Views, Main View".
