Merge pull request #33 from whoisglover/travis-ci

added travis.yml file after having the travis-ci turned on
fixed user#show test to accurately reflect changes in logic

The user#show method now returns a hash that includes the student and
their submissions.  This new structure broke a controller test, this commit fixes that.
