Create a makefile for easy local development.

A few useful commands:

# Start development server with hot reload:
bundle exec jekyll serve --incremental

# Run test
bundle exec htmlproofer ./_site --check-html --disable-external

# Install ruby gems
bundler install

I think a Rakefile would be a better fit, because this project uses Ruby.

Yeah I don't mind both, the commands we need are fairly simple.
