ar_innodb_row_format.rb initializer does not work with Rails 5 due to deprecation of alias_method_chain

[joshweir]

As alias_method_chain is deprecated in Rails 5, I have rewritten the ar_innodb_row_format.rb initializer to make use of #prepend. I found more info on this type of conversion here.

ActiveSupport.on_load :active_record do
  module AbstractMysqlAdapterWithInnodbRowFormatDynamic
    def create_table(table_name, options = {})
      super(table_name,
            options.reverse_merge(
              :options => 'ENGINE=InnoDB ROW_FORMAT=DYNAMIC'))
    end
  end

  ActiveRecord::ConnectionAdapters::AbstractMysqlAdapter
    .send(:prepend, AbstractMysqlAdapterWithInnodbRowFormatDynamic)
end

I'll submit a pull request for this.
