Foundational concept design: task attributes

RFC link: Tasks and Attributes

We'll need a set of the most basic task management concepts: tasks and their attributes, including:

• basic attributes: task title, creation date
• extended attributes (various Taskwarrior stuff, including Taskwarrior task UUID, priority, tags etc.)
• volatile attributes (Taskwarrior)
• cross-task dependencies
• ~~an algorithm to detect dependency loops (Taskwarrior disallows them, but they still may be introduced if a conflict occurs)~~

Depends on:

• [ ] #22
• [ ] #39

• an algorithm to detect dependency loops (Taskwarrior disallows them, but they still may be introduced if a conflict occurs)

I consider this out of scope of the task at hand.

RFC for this issue has been merged: https://github.com/ForNeVeR/praefectus/blob/master/docs/rfcs/tasks-and-attributes.md

This issue will be closed after adding a rough implementation of described concepts in #22.
