Behavior of the *cider-refresh-log* buffer is distracting

[luxbock]

I usually only care about the results of calling cider-refresh if there was a problem. If there were no problems I would much rather just get a message in the mini-buffer. Right now the behavior of the *cider-refresh-log* buffer is to pop-up in the other-window, which is annoying because I was already using that buffer for something else I care about. I would therefore propose the following changes to the behavior of running cider-refresh:

• If there were no problems, log everything as usual but don't pop-up the log-buffer. Display a short message in the mini-buffer letting the user know that the reload was successful.
• If the reload failed, display the log-buffer in the current-window. This way the user can see what failed, and get rid of the buffer by pressing q without having to change windows.

This is a duplicate of #1239 //cc @cichli

@luxbock I've added cider-refresh-show-log-buffer now (defaults to nil) - let me know what you think next time you update?

Thanks! Works just as I had hoped.
