Option to hide the digital timer

[vin047]

Cleans up the interface, for users who don't like the digital timer or find it useful.

Depends on #125.

Link Height tasks by mentioning a task ID in the pull request title or commit messages, or description and comments with the keyword link (e.g. "Link T-123").

💡Tip: You can also use "Close T-X" to automatically close a task when the pull request is merged.

Thanks for all the PRs. I'm excited to see another dev adding to the project! 🎉

Could you make each PR self-containing without the requirement of another PR. That way we can review the PR on the changes (what it fixes or what new features it implements) without having to merge another PR. I understand there will be repeat code.

Hey @karbassi, thanks for the warm welcome. Glad I can contribute to this project!

Current look

This PR

Its an optional setting, and defaults to the current behaviour, so shouldn't affect other people if they don't like it.

The first 2 commits of all the PRs I've submitted are actually all the same (adds the View menu option and saves/loads preferences from UserDefaults) – in other words, the PRs are already self-contained and can be merged without needing #125. I only split it up like that to make it easier for code review. But happy to close that PR if you prefer.

Let me know if this is ok. I'll then fix up the lint issues that have been flagged.
