 {{{
     Run 'run_tests.py --all' with python 2.6.
     Run 'run_tests.py --all' with python 2.7.
     Run 'run_tests.py --all' with python 3.x.
     Run 'run_tests.py --all --target ONLINE' with python 2.7.
 }}}

 Here's what I need to do:
 * check to see if Travis supports python 2.6, and add a job with 2.6
 * make the 2.7 job --target ONLINE
   * assuming that ONLINE is a superset of offline
 * make the latest python 3.x job --target ONLINE
   * assuming that ONLINE is a superset of offline

 I'm modifying existing jobs to save build time: we could create separate
 jobs for ONLINE, but that would add ~5 minutes to every CI run.
