Get rid of relative imports in all unittests. Now anything that imports e.g. test_support must do so using an absolute package name such as "import test.test_support" or "from test import test_support". This also updates the README in Lib/test, and gets rid of the duplicate data dirctory in Lib/test/data (replaced by Lib/email/test/data). Now Tim and Jack can have at it. :)
