Make commit details view collapsible recursively

[ToBoMi]

In larger commits with files changes in many folders with subfolders the commit details view gets many entries that one needs to scroll through to changes in a specific folder.

If one needs to view a specific folder only one needs to scroll a lot or collapse some or all folders by hand.

It would be nice to be able to collapse all folders inside that view recursively by a button (and recursively expand it if it is collapsed)

I cannot believe there is no issue for this yet, but I am unable to find it.
