Title: Add py26 back to .travis.yml but make it an allowable failure

Here's an example set of Travis builds: http://travis-ci.org/#!/msabramo/tornado/builds/1638919 -- note that the 2.6 build failed with the segmentation fault, but the overall build is still marked as green because the 2.6 failure is an allowed failure.
