Places Panel: Allow hiding of items

Related changes:
- Animate changed items for the details-view in case it is not expandable
- Remove the hardcoded "isHidden"-code in KStandardItemListWidget and
  allow derived widgets to define themselves what means "hidden" within
  their context.

The current code needs a lot of bugfixing, but lets make this in smaller
steps during the next days...
