Parallel tests

[derchrisuk]

With the current setup, it is not possible to run parallel tests.
They are started using the following CLI options:
--env env1,env1

If I try to pass this to the grunt plugin, I get the following error:

$ grunt nightwatchjs:chrome,firefox
Grunt and task output will also be logged to "./grunt-log.txt"

Warning: Task "nightwatchjs:chrome,firefox" failed. Use --force to continue.

Tried fixing it by removing the '=' from args, and replaced it by a blank, but this was throwing another error.
