Calling :cmd:title:`<cmd>` will generate a cross reference to `<cmd>`, but unlike :cmd:ref: which displays a literal block and puts the title (short_help) in the hovertext (the title field of an a-ref), :cmd:title: will display "<cmd> - <short_help>" as plain text.
Thus replacing the previous use case of referring to :doc:`cmd/<cmd>`.
Also refactor util py scripts to have more descriptive names.
