Have a context menu to clear review status

[bpasero]

Here in "File" node there could be a context menu to either check or uncheck all checkboxes:

If you use a tree structure for files then you get this by checking/unchecking a folder checkbox.

A few ideas for the flat structure:

• Support multi select, then you select all so toggling 1 checkbox would toggle all.
• Add a checkbox on "Files"
• Add an inline action on "File" for "mark all as viewed"/"mark all as unviewed"

I like the idea of multi-select!
