Slack plugin for sending messages to webhooks

[Brayden]

Purpose

Plugin that sends a Slack message based on a defined Slack webhook and supports sending advanced message formatting (https://api.slack.com/messaging/webhooks#advanced_message_formatting). Very simple implementation that helps with communicating changes, issues, and more directly from a Starbase instance.
