Protractor tests with multiple chrome profiles

Runs the protractor default test with webdriver and selenium in chrome (#193 and #194).
 
`gulp profile1` or `npm test` will load profiles/protractor.config.js and use the default chrome data directory/profile.

`gulp profile2` will load profiles/another.config.js and use the data directory specified therein (edit path prior to use). Note that the first time I ran it seemed like the browser just 'hung', but I think that was due to another extension looking for updates.
