Take a page offline

[penbea]

No idea if this is the correct section to log this, however, it'd be great to be able to change a page from being live and online to it being offline. I find this really useful when slowly building a page, still being able to create other updates such a blog posts as I do without publishing the unfinished page. I'd also prefer not to have it show in the navigation bar when I'm editing the unfinished page, like the membership and password options allow me to do.
