How do I write an plugin that has it's own event loop / listens for github updates?

This issue will automatically be closed if you merge #78

Regarding listening for Github updates, my plan is to create a "web" plugin (#58) that would allow Github to call a webhook on it. I wanted to avoid forking / threading each plugin in Cardinal (i.e. allowing them to run an event loop.)

I'm not sure this is the most valid approach, but I have ideas on the web plugin being extensible in other ways as well (i.e. #71)

This is awesome! Just made a couple tweaks for consistency. Thank you very much.
