removed the tags stuff Noah put in last night as it was breaking ability to use the site
added tagsinput-rails to gemfile, bundle installed, added it to application.js and application.css as well
removed some superflous code from tag JS and added a tag-div class for styling them (i.e. not taking up full width of page and centering the tag box)
Merge pull request #34 from gregburton/master

tags working (but need work)
