Bring Treema to Bower

I added necessary files and changed the file describing the usage of it. However in order to work perfectly we should figure out the exact dependency of jQuery and jQuery UI. Bower will at the moment install all dependencies properly however the jQuery version that is currently specified as dependency does not offer a `bower.json` that specifies the main files. This means that if someone uses something such as [grunt-bower-install](https://github.com/stephenplusplus/grunt-bower-install) to automatically include scripts into their project, jQuery needs to be included manually. 

If we can figure out that it supports newer versions of jQuery (which should be the case) we can update the `bower.json` and fix this issue. At the moment you can test the bower installation using:

```
    bower install git@github.com:dkundel/treema.git
```

If you want to see the problem I'm talking about run afterwards `bower list --paths` it will show the correct paths for everything but jQuery.
