Make the travis.yml read the db name from the package.json?

[glebec]

In theory we could add a script which outputs the db name, then use that from within travis.yml in the before_script field.

• Pros
  • students wouldn't have to remember to update the project name in as many places
• Cons
  • adding more cleverness to what is supposed to be a student code scaffold
  • removing an opportunity for them to interact with and understand travis.yml

I'm leaning towards not doing this, but figured it wouldn't hurt to make it an open discussion.
