A Couple of Fun Updates

• minor
  • update /jobs to return an array of jobs, sorted by creation date descending
  • return the full uri for log_route so it is clickable in the browser (also return info_route, which is the route for the individual job)
  • add the ability to filter (by multiple filters) /jobs by adding a query string parameter
  • default build when no Bobfile present (runs docker build -t $(basename $(pwd)) .)
• patch
  • /jobs/:id does not include stderr message if job fails during setup
  • simplify release process (only shipping binaries, not tarballs)
• other
  • simplified makefile
  • some refactoring
  • adding go tip to travis build matrix
