Fix Bootstrap and Login

Hi Kailey,

With a little trial and error, it seems as if I've been able to fix the issues that you were facing. 

As far as Bootstrap, you were missing the "@import" lines of code in "bootstrap_and_customization.css.scss."

To fix the login issue, I went back to that StackOverflow issue page that I had sent to you earlier and edited the code in the "_search.html.erb" file under "/pins." It looks as though you were originally specifying an action in the Pins controller that didn't exist (that is, "search"). By editing the file a bit, I was able to bypass that for you. Be sure to check back in with the StackOverflow page to see more information on this fix.

Let me know if you have any other problems, and I'll do my best to help.
