Ignore _pdo.log
Default port of not localhost in init()
Use regular links without data-request and let internal link listener handle ajax
Avoid home link being /posts/ instead of /

Set url to URL . /posts/$post->url if not home page. Otherwise, just URL
Fixed typo (connect->port to $connect->port).

Was setting default port to the string instead of variable. Only affected
non-localhost connections.
Removed handling of unused $_POST[post].

It was an old way of handling ajax navigation that is now handled by listeners
on internal links.
