this has the exact same syntax as tera (jinja style) but its compile
time which is very useful for having a portable binary that doesn't
require any files to run like a templates folder or public folder.
i added a json api called /name which lets you get the previous and next
site name. i also modified the internal url functions to return a None
value if overflow is turned off and next or previous is nothing.
you put your sites url into the url query and it should redirect you to
the next or previous site and it will overflow if you're the last or
first site in the array.
