Merge pull request #33 from Noahhh/master

Working on tags, page  broken at the moment
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)
trimmed down amount of JS associated with tag form substantially. Moved it into proximity of notes area of discover page. Intial attempts to remove assoications to remote JS and CSS were not fruitful.
further refinement of tags. added explanation that a tag cannot contain a comma, since commas are used to separate tags. tags are not currently being saved anywhere; when you refresh the page, they go away.
populated a list of example tags
