mythfrontend depend on X to show verbose options in console

[kenni]

As far as I remember, this is a regression in 0.25. Mythfrontend fails to display the list of verbose options when a X server isn't available, even though no X server should be needed.

[kenni@mediaserver ~]$ mythfrontend --verbose help
mythfrontend: cannot connect to X server 

[kenni@mediaserver ~]$ mythfrontend --help
mythfrontend version: fixes/0.25 [v0.25.1-59-g61e7a0e] www.mythtv.org

of recording rules.
