Patch request - menu modifications

[David Masterson]

I'd like to request two simple changes to the basic Emacs menus:

1. Add dired-quit ('q') to the dired menus.  It would make it easier to
traverse a directory tree using just the mouse (click directory to
descend and click dired-quit to return up). To me, it is not obvious
which menu to put it in.

2. Add kill-this-buffer to the "Buffers" menu.  The funny thing is that
where-is reports it as "<menu-bar> <file> <kill-buffer>", but I don't
see it there.

bars) of 2020-12-14"
