Avoid prompting on doc, source, argument inspection

[arichiardi]

Hi Bozhidar,

I would like to add an option that disables prompting at every inf-clojure-show-* function.
Cider's workflow is way more fluid. I was wondering whether we should have a defcustom for each and every command or a global one. Probably the latter.

Thanks a lot!

In cider it's a global config. I'm fine with adding a config for this here as well.

Should the recent inf-clojure-prompt-on-set-ns become global then?

Yeah, guess that'd be best. I totally forgot about it.
