HTML5 pushstate support

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install this youtube user script 
https://greasyfork.org/en/scripts/4712-clean-loopy-for-youtube
2. Go to youtube and click a video. The userscript is not executed.
3. If you refresh the youtube video page, the userscript is executed.

What is the desired output? What do you see instead?
Userscripts should execute on sites that uses AJAX and HTML5 pushstate

What version of the product are you using? On what operating system?
Tampermonkey 3.9 in Chrome 38.0.2125.111 m on Windows 8.1 64-bit (with latest 
updates).

Please provide any additional information below.
Youtube loads new pages using AJAX and then changes the URL using HTML5 
pushstate. Tampermonkey is not able to detect this change via pushstate, so 
scripts for youtube video pages do not work without refreshing.

history.pushState only modifies the displayed URL there is no real page 
(re-)load. 
That's why this must completely be handled (via a listener or by disabling) by 
the script itself. Tampermonkey is not the right place to take care of this, 
cause the userscripts would be injected multiple times into the same 
environment.
