Ability to specify site home card

Ticket

+commit
 
I'd like to be able to change a sites home page independently of changing the site name. Currently the sites home card is controlled by System.site_name in wagn.rb. For my personal wagn I'd like my site name and user account to be the same, but I don't want my user card to be my home page.

 

It's in *home (as of Wagn 0.10).

 

I like to be able to set the sites home page from the admin sidebar.
