// @name URLs Need Titles
// @namespace UNT
// @description When you paste a URL to a friend, it is useful if it contains the title of the page. This script adds these missing titles for common websites using # part of URL. In other words, it turns non-semantic URLs into semantic URLs!
// @version 1.3.3
// @include http://*/*
// @include https://*/*
// @grant none
// ==/UserScript==
// For example, this script will change this address:
//
// http://www.imdb.com/title/tt1155592/
//
// into this address:
//
// http://www.imdb.com/title/tt1155592/#Man_on_Wire_(2008)
//
// which is far more useful to paste to other people.

changeTitle: true / false, Some of the rules do not change the URL,
but change the page title instead. This
can be useful for bookmarking.
hostMatch: "youtube.TLD", All subdomains will be accepted, e.g.
somewhere.youtube.com. TLD will match one
or two toplevel domain elements, e.g.
"youtube.ath.cx" or "youtube.net".
pathMatch: "/watch", This regex will be wrapped with ^..$ so use
.* at either end for wildcards. Note that
path does not include the search part of
the URL, "?q=squash&type=image". Filtering
on this part of the URL may be added later.
If left blank all paths will be accepted.
getTitle: function(){...} A function which returns a sensible title
for this page. If left blank will just
grab document.title.
