fix :plugin_install in case of github name has numbers
need 'require "yaml"' for Ruby 2.1.0p0

I had an error like this:

home/babie/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/earthquake-1.0.0/lib/earthquake/core.rb:57:in `default_config': uninitialized constant Earthquake::Core::YAML (NameError)
