version of browser-sync module

[lazylester]

it's beyond my skill set to determine why... but this package only produces the expected result from the gulp command if you upgrade the browser-sync version to "~2.2.2". (I copied this over from the gulp-starter project https://github.com/greypants/gulp-starter)

In package.json, change the browser-sync spec to "browser-sync": "~2.2.2"
