Improve recents view

[rdbende]

These would be nice to have:

• Initiate the drag and drop operation with the item's real path, as the recent:// URI doesn't work in most places.
• Add an option to copy real path
• Add an option to show the item in the containing folder
• Add an option to remove the item from recents

I've assigned the issue to myself but you can also take it on yourself if you want. In that case, I can offer help if you need any.
