Allow VenoBox to be installed via bower

Hi Nicola,

We use [bower](http://bower.io/) to install all of our 3rd party plugins. I created a bower file for you and marked the version as `1.2.2`.

If you accept this pull request please do the following:

1. Create a tag and push it
```
git tag -a v1.2.2 -m 'Release 1.2.2'
git push origin --tags
```

2. Register the package with bower
```
bower register venobox git@github.com:nicolafranchini/VenoBox.git
```

Once that is done your project should be available on the bower registry:

If you need any assistance please let me know.

Cheers,

Ryan
