Apply JSCS and JSHint to the protractor test files / Update deps

[shinnn]

• I updated the settings of the lint task and .jshintrc to apply JSCS and JSHint to the protoractor test files.
• I fixed coding styles according to the report of JSCS and JSHint.
• I replaced async with async-each-series.
  • This project doesn't use the gadzillion methods in async.
• I updated dependencies and devDependencies.
• I updated bin field of package.json.

  • According to the documentation of package.json:

    If you have a single executable, and its name should be the name of the package, then you can just supply it as a string.
