Publish browser version to Bower

[cburgmer]

Prepare for release of the browser build through Bower. This will allow an easy bower install cssom.

The commit

• adds bower.json
• adds built CSSOM.js to repo under dist/ and adjusts the Jakefile

When this is merged, a final step is needed once to publish the package to Bower (see https://github.com/bower/bower#registering-packages):

$ bower register cssom git://github.com/NV/CSSOM.git

In the future however to update the published artifact it needs to be rebuilt and checked into the repo.

Hi @cburgmer, we have no intention of checking in build artifacts to the repo. If you wish to do so in your fork, you can, and maintain any bower registration or publishing. We are happy with npm and advise consumers to use that.
