URL (protocol, hostname, path) in title 1.0 Compatible with Firefox 57+

by Tormen

Adds the URL of the tab to the windows title:
* optional delimiter (e.g. ' - ')
* optional protocol (e.g. 'http://')
* hostname (e.g. 'foo.org')
* optional path (e.g. '/foo.php')

This is for instance useful for keepass/keepassX.
