#### Updates
##### v0.65 7/16/15 by DW
In prefs.json a new value, error404File, defaults to prefs/error.html
When there's an error, we read that file and send it back as the text of the 404 response.
The default value is more or less exactly the same text earlier versions of PagePark returned. It's actually in HTML, that's the difference. As opposed to being plain text.
##### v0.64 7/7/15 by DW
I wanted to do a site redirect that was more than just a domain name change.
