Deadlines#102

Suggestion
Deadline date field

Implementation
Allow tasks to specify a deadline date. If specified tasks will also show on the calendar on that deadline date, with a deadline icon 🏴 before the task name.

Use Case
Sometimes tasks need to be worked on multiple days, and they can be too chunky to breakdown if you want to keep the context in one place (task). As you move this task between days on the tweek calendar it can be hard to remember what the real due date is for this task. With a due date field, you can also be sure to know when it needs to be done by.

I am in college so this would be awesome!
