Test switching to google search box

[laritakr]

Replaced existing search box with a google search box. Refers to #109

TODO:

• Needs some CSS work to position search box.
  
• Need to handle baseurl in dev mode (currently commented out in _includes/google_search.html)
• is currently based on my ND google account. Need to decide where to set up the custom search (see https://cse.google.com/cse/)
• there are several configuration options in custom search. I used the overlay option but we could change this.
• Also has an issue with the paths behind the popped up search results... seems to not be finding some js and css. If you use the X to close the search results, you get the unformatted page)
