Summary:
Fix a TODO : InformationPanelContent::configureSettings code is moved to InformationPanel::contextMenuEvent
Adding necessary accessors and changing visibility of one slot.

Test Plan:
1 compile
2 in dolphin right on the information panel
3 toggle preview
4 from the same context menu, click configure, metadadata settings appears
5 toggle "condensed date" if available
