fixes #3: remove actual version check and preserve resolutions

Fixes #3

So I included the suggestion that @rwjblue had, as well as I'm preserving the resolutions. Now in your scenario files you can optionally specify a resolutions object, like this:

module.exports = {
  scenarios: [
    {
      name: 'ember-release',
      dependencies: {
        "ember": "components/ember#release"
      },
      resolutions: {
        "ember": "release"
      }
    },
    {
      name: 'ember-beta',
      dependencies: {
        "ember": "components/ember#beta"
      },
      resolutions: {
        "ember": "beta"
      }
    },
    {
      name: 'ember-canary',
      dependencies: {
        "ember": "components/ember#canary"
      },
      resolutions: {
        "ember": "canary"
      }
    }
  ]
};

or if you are not using shims, you can specify something like this:

module.exports = {
  scenarios: [
    {
      name: 'ember-release',
      dependencies: {
        "ember": "ember#release"
      },
      resolutions: {
        "ember": "release"
      }
    },
    {
      name: 'ember-beta',
      dependencies: {
        "ember": "ember#beta"
      },
      resolutions: {
        "ember": "beta"
      }
    },
    {
      name: 'ember-canary',
      dependencies: {
        "ember": "ember#canary"
      },
      resolutions: {
        "ember": "canary"
      }
    }
  ]
};

I believe this should fix that problem that you had with the canary channel.
