Innovare-Bundle

This PR aims to:
* generate the Innovare-Bundle
```
php app/console genrate:bundle
```
* use the Bundle Inheritance to Override parts of a Bundle

#### Notes
It is not possible to have two bundles extend the same bundle with bundle inheritance.  Bundle inheritance can only be linear. 
```
SonataPageBundle -> SonataDemoBundle -> InnovareBundle.
```
