NUSBot Handler

[kennetham]

Separate handler logic from main file

• [v0.3.27] Refactored & added QueryPattern 9c66490

Ideally, a listener to poll for events, and a command handler to accept different commands rather than a long switch case.

bot.listen(:method => 'poll', :interval => 1)
bot.on :command, 'help' do #=> Refers to /help
  send_message("Help message")
end
bot.on :text, 'how are you' do
  send_message("I am good. How about you?")
end
