I updated and trimmed many outdated features.

Update April 2021: I fixed most obvious errors but many more improvements are needed. I'll work on them soon!

Fix and improve the display and behavior of set parent switch

- Fix file attachment shortcut by matching class name with the current Asana UI
- Support number HTML entities in text replacement

Fix display issues by matching class names with the current Asana UI

Improve the display of sibling subtasks arrows in comment-only tasks

- The number of text replacement is displayed on the toast notification (for user-defined strings). I also fixed a bug with "Use Preset Cleanup" feature.
- I added keyboard shortcuts to attach files (Tab+V and Tab+1/2/3/4/5).
- I also added a keyboard shortcut to open more actions (Tab+.).

Support special replacement patterns for Use Preset Cleanup feature

I started this Asana Navigator project because I didn't really like [the change to push down the project list](https://forum.asana.com/t/ui-change-project-tabs-buttons-in-tasks-pushed-down/20394). I'm happily dropping the feature to display the project names on top of the task pane, because of [the improved task pane layout](https://forum.asana.com/t/we-re-updating-our-task-pane/70641). I'm grateful to the Asana team for listening to and valuing our voices :)
While I love Asana's new task layout on the right pane, some features didn't work with the new layout. I fixed the issues and all features should be fully functional now.

While I love Asana's new task layout on the right pane now being rolled out, some features didn't work with the new layout. I fixed that issue.
