Add Event Command to New Follows/Subscribers

I would like the ability to link to a command(s) for each platform when a new Follow or Subscriber happens on that platform.

I personally would like to be calling up webhooks to IFTTT (so having IFTTT compatibility would be awesome as well, but I can do it from a webhook). 

Essentially; New Follower on Twitch -> triggers the linked event -> lights blink purple in room.

New youtube subscriber -> triggers linked event -> lights blink red...
