Make default wiki page as a setting
For now, the default wiki page is home，and the page 'home' is also the wiki page title.
I am a Chinese user, so I want to write and name our wiki in Chinese, so it's not home, I want to name it 首页，when I do this, and click Wiki navigation, it navigate me to create a new home wiki. That's not want I want.
Option 1, Make default wiki page as a setting, then I can set the default wiki page as 首页 Option 2, Add a Title property, so I can name wiki page home, but show Title on page and page navigation.
I think maybe the option 1 is more easier to do.
