ENH Make year and quarter dash-separatable
This closes #9688 by making years and quarters separable by dashes.

@jreback I think I've adjusted them accordingly, although I'm not quite sure about the how you want the test-case class. Anyhow, tell me if it looks OK so I can rebase it :)
 minor comments, pls squash as well. thanks. ping when green.
 @jreback That should do it, commits are now squashed.
 thank you!
 Happy to help, pandas has saved my ass too many times to count.
