Title: Tip for adding custom headers on tests

Explain how to add custom headers for tests based on zope.testbrowser.

Removed a dead link as a bonus.

As I had to do some tests that need custom headers set on requests I realized that the documentation here was not so up to date, so I took the time to update it :)
