Title: Fix changed for yum group

- Fix setting changed correctly for a yum groupinstall.
- Added an example for installing a group with the yum module.

I tested with the following tasks/main.yml

```
- name: install 'Development tools'
yum: name="@Development tools" state=present
```

Could you take a look?
Thanks!
