Subject: [PATCH] [travis] Run tests in parallel

[test_download] Print test names in case of network errors

[test_download] Add comments for nose parameters

[test_download] Modify outtmpl to prevent info JSON filename conflicts

Thanks @jaimeMF for the idea.

[travis] Only download tests should be run in parallel
