Show urgency in query outputs

[FilSalustri]

Whether or not I sort by urgency in a particular query, I would find it very useful to know the urgency of a task.
The use case is, in the general case, being able to visually scan the tasks in a query result and quickly spot the tasks with higher urgency.

It could be a toggleable feature that users can turn on in Tasks' settings.

Visually, it could be something quite simple, like a small coloured square at the start of a task, right after the checkbox; ranging from bright red for high urgency to something cooler, like blue, for lower urgency.

If accessibility is a concern (i.e., for users with certain kinds of colour blindness, say), one could optionally put the actual urgency value as text inside the coloured square.

Interesting idea. I'm thinking of the simplest possible thing, of showing the numeric value, and adding an option to display it.

Perhaps adding an instruction show urgency.

And if #1088 is implemented, then optionally adding a table column for urgency too.

[FilSalustri]

That's quite reasonable.
Maybe, in the future, if the feature becomes popular, then one might consider alternate renderings of urgency.
But to kick it off, just displaying its value (and possibly adding a column for it in case of an eventual tabular format) would work (for me, at least).

Great idea. Getting feedback about the urgency values would also help in improving the algorithm for calculating the urgency (see #691).

I ahve suggested an implementation in PR #1139 now.

[FilSalustri]

I like it. That would totally work for me.
