Recent updates
--------------
	22.09.2006 11:12	Created a new separated distribution with all the code in one sngle file
	19.10.2006 09:35	Added crossdomain support to Ajax object, using JSON
	01.11.2006 09:45	Changed the project's name, "tsrvod" to "tsrkit"
	28.02.2007 18:35	Included prototype.js, and simplified a couple of things with it


Code convention used in this project: http://javascript.crockford.com/code.html

TODO: an invalid xml ajax answer seems to give "no result" instead of an error

TODO: replace innerHTML with nodeValue, it's better because it's less worse (and it's valid)

TODO1: Since this won't only be used for videos, replace all the occurences to "video" by "item",
       and "playlist" by "search", or something like this
	   
TODO firstly : translate the doc in french, for the french developpers of the TSR
