Create example HTML files to test the deprecated

I created a test page, index.html which you can find in the root of the project, in the example-html-files directory:

You can use these fields to tests the jQuery deprecated functions, I plan to add more, once I add more deprecated files, this is a work in progress, but I think this is good for now.

Sending this to "Needs Review" if anyone wants to have a look on it.

I'll move it to the 1.0.x branch for now, I plan to create some more tests, in addition to the PHPUnit tests of course.
