seleniumArgs should have a default

[tarjei]

If I try to run with a config like this:

exports.config = {
  // The address of a running selenium server.
  //seleniumAddress: 'http://localhost:4444/wd/hub',
  seleniumServerJar: './selenium/selenium-server-standalone-2.35.0.jar',
  chromeDriver: './selenium/chromedriver',

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },

I get an error:
/home/tarjei/htdocs/frisvold/selenium-tests/node_modules/protractor/lib/cli.js:115
config.seleniumArgs.push(
^
TypeError: Cannot call method 'push' of undefined

Adding seleniumArgs solves this. Wouldn't it be better to just default seleniumArgs to []?
