Unlock Mocha dependency

[lolmaus]

ember-mocha/bower.json has mocha locked at 2.2.x. Is there a reason for that?

There is at least one annoying bug that has been fixed in Mocha 2.3.x.

Please upgrade.

I've submitted a PR: #69 .

Meanwhile, the workaround is to update bower.json. Thank druids, Bower's dependency list is flat. You wouldn't be able to pull that out with npm.

{
  "dependencies": {
    ...
    "mocha": ">=2.3.4",
    ...
  },
  "resolutions": {
    "mocha": ">=2.3.4"
  }
}
