#43 Server mainmodule: better GUI

[Alexander Rayborn]

The GUI to start services in the server main module
needs to go a bit further (probably doesn't need to be
said, but I thought I'd like them out anyway):

1. Need to show start/stop status of the service. If
it's started, show the option to stop it instead of
start it. This is a nailbiter because if you start the
firewall/NAT service, the other services will start but
not accept connections.

2. Submenus to configure options on the services.
e.g. on bind, a submenu to create a new zone. On the
firewall/NAT, a submenu to open/close ports.
