Add the ability to sort issue comments

Hi,

it would be nice if you could sort an issue that has a very long comment trail to sort it from new to oldest. reason for it if you know about the issue and you have been committing already you don't want to scroll to to bottom to read then nest comment.

Way Read this Hard to It's really

Though I would love to have an option where already read comments are reduced kinda like how gmail does:

cant you could put a button the the form and where the user clicks it. The database then gets a request for all comments linked to this issue order by ASC or DESC

simple sql - I know this SQL is not right for this database its just and example

SELECT * FROM Comments WHERE IssueId = 'xxx' ORDERBY CommentId ASC or DESC

I've created a PR, but not sure where is the FE part of it
