Integration: Gmail / GSuite#187

So one can easily create a task in Slash from an email

• Editable title / list / notes
• Add URL to email in the notes so it auto-opens when you start the task

Implement a sidebar using the Google Workspace Add-on API so that you can be installed via the Google Marketplace, that shows your lists and tasks, and allows you to create tasks from an email (that has a URL back to the email), as, like many, much of my work comes via my inbox.
