Check for UAA-style keys to save heartache

```ruby
require "kato/config"

def check_config hash
  hash.each do |key, value|
    if key.to_s.include?('-')
      $stderr.puts "WARNING: Config key #{key.inspect} contains a hyphen. AOK-style keys use _ to separate words."
    end
    check_config(value) if value.kind_of?(Hash)
