VIRA-10: issue time tracking

[n0v1c3]

As a user I would like to be able to track the time I spend coding as required on some projects. I would however, like this tracking to be as close to accurate as possible to my actual work and not my walking away and leaving vim running.

As I have been working on VIRA-253 this has started to become a real thought. Between async and a database we should be able to keep track of things quite well. "Once the db works"
