Code-style update. Used the .jshintrc from bower/bower and then fixed linting
Several more CS changes:
- Removed lots of unhelpful comments (no need for a comment with the filename
  in, for e.g.)
- Removed some extraneous whitespace
- Run JSHint on the tests too
- Reformatted the JSON responses in couch-mocks
Merge pull request #31 from wibblymat/code-style
