activitywatch: add module

[foo-dogsquared]

Description

Adding ActivityWatch service which is fully intended to be local for the user so adding this to home-manager is a nice fit.

This service is fully deployed and managed by systemd instead of the traditional way of using it by running aw-qt which opens up a system tray.

Rebased the PR to current master revision and also updated the tests and the news item.

Is this going to be merged anytime soon?

Seems I accidentally made review comments instead of real comments so they never showed up 🙁

By the way, there is no need to add a news item, we can add it when doing the merge. To help avoid these merge conflicts.

All right, I've pushed with the suggested changes and added a new test.

Got it.

Thanks! I made a few minor final fixes, mainly to reduce the download size for the tests. Merged to master now 🙂
