Several Fixes/HTML-Enhancements 

1. Product support details in BS new panel `oc-panel/product/create` and  `oc-panel/product/update`
2. Calendar icon for date input fields `oc-panel/product/create` and  `oc-panel/product/update`
3. Display form-group div only if there are images `oc-panel/product/update`
4. Missing form-group div `oc-panel/product/update`
5. Conditional unnecessary, controller is always product `oc-panel/product`
6. Tooltips added `oc-panel/product` (Do the same on other views with buttons?)
