Add opsdroid to ChatOPs tools

[kchong5463]

What is this Python project?

This framework is designed to take events from chat services and other sources and execute Python functions (skills) based on their contents. Those functions can be anything you like, from simple conversational responses to running complex tasks. The true power of this project is to act as a glue library to bring the multitude of natural language APIs, chat services and third-party APIs together.

What's the difference between this Python project and similar ones?

It is designed to be extendable, scalable and simple.
