Remove some gems in the Gemfile (PR #36)

I’ve remove the lines in the Gemfile below:

gem 'haml' # I've converted all the haml files to html.erb
gem 'slim', '<= 1.3.0' # There is no slim file in this project
gem 'test-unit' # We are using Rspec


Looks good, but can you fill this out first? Thanks

@eviltrout All right, I’ve filled it :blush: .

Thanks so much!

Actually looks like sidekiq requires you to include slim, so I have to put that back in!
