[TASK] Improve click area of new content element wizard item

The clickable area of a new content element wizard item
is improved now.

The <a>-tag was added around the Bootstrap 3 media object
childrens which makes it easier now to add a new content
element by clicking anywhere on the item.

The text shows also the hover-style when an editor hovers
the icon of a NCEW item. The user experience for editors
working on touch devices is also improved by this.
