- Restoring focus to previous (taskPane) panel after closing modal (works only when invoked with shortcut)
- `projectPane.RemoveActivateProject()` and `taskPane.ClearCompletedTasks()` do comply with `func()`. So no need to wrap within `func() {}`
- Fixed issue - Project dosen't exit with Ctrl+C once (maybe because of re-running `.Run()` in `AskYesNo()`).
- When focusing back to tasklist from task detail, re-showing projectDetail pane
* added shortcuts '+', '-' and 'o' for date selection shortcut
* underlining shortcut key for those and 'e' (Edit description)
* Moved set due date logic in separate functions
- **Today:** Display tasks of today and overdue
- **Tomorrow:** Tasks scheduled for tomorrow
- **Upcoming:** Tasks scheduled for next 7 days
- Keep "Today" focused on starting
- Order Tasks of dynamic list by Project
- Parsing date input using local TZ - Fixes#7
