Browsers are merged not overridden

[pflannery]

In the documentation here it says that we can override the browsers array with different browser specs but I've found that it's only merging them.

So if I have

karma: {
  options: {
    runnerPort: 9999,
    browsers: ['Chrome', 'Firefox']
  },
  continuous: {
    singleRun: true,
    browsers: ['PhantomJS']
  }
}

and I run grunt karma:continuous I end up with

['PhantomJS', 'Firefox']

Only browsers[0] from continuous gets overridden but browsers[1] from options is left intact.

Can I suggest changing this line here to:

data = _.merge(options, data)
data.browsers = this.data.browsers;

I can PR if there isn't something I'm missing?
