Fixing the issue of visiting a project fork url giving 500 error when not signed in instead of being redirected to the sign in page. The main reason is ApplicationController skips authentication if the project exists. To fix the issue, forced the authentication in ForksController when current_user is nil.

Remove order-dependent expectation

Fixes #24341, hopefully

Change auto selection behaviour of emoji and slash commands to be more UX/Type friendly

## What does this MR do?
In the context of a special command (starting with "/", ":", ...), the MR disables auto selection of first item in the dropdown suggestion menu, until at least a character has been typed.
This behavior change originated from #22058 and #23578 in which problems with the ":" special command were pointed out.

## Are there points in the code the reviewer needs to double check?
At lines +187 and +242 there were originally no sorters. Given what ``DefaultOptions.sorter`` does, I don't think it is a problem.

## Why was this MR needed?
To solve #22058 and #23578

Remove an extra leading space from diff paste data

## What does this MR do?

Remove an extra leading space from diff paste data.

## Are there points in the code the reviewer needs to double check?

I have checked the following three patterns.

* inline diff
* parallel diff
* blob preview

## Why was this MR needed?

Diff paste data contain an extra leading space.
So it need to remove an extra leading space manually from pasted diff data.

disable markdown in comments when referencing disabled features

This MR prevents the following references when tool is disabled:

- issues
- snippets
- commits - when repo is disabled
- commit range - when repo is disabled
- milestones

This MR does not prevent references to repository files, since they are just markdown links and don't leak
information.

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6598 introduced new
JIRA settings, but that's not yet released. Since our documentation is currently
built using the master branch, users are having issues where the docs show
different settings than what GitLab's latest stable release supports.

It was previously possible for invalid credential errors to go unnoticed
in this task. Users would believe everything was configured correctly and
then sign in would fail with 'invalid credentials'. This adds a specific
bind check, plus catches errors connecting to the server. Also, specs :)

Improved build page scroll UX

## What does this MR do?

This MR smoothes the UX of the builds page by more effectively affixing the scroll step buttons.

It also ensures the scroll step buttons are always in view, even if the sidemenu is open.

It also moves the autoscroll button into the same container as the scroll buttons.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The build scroll buttons are always in unpredictable places and are often hidden behind sidemenus.

Replace jQuery.timeago with timeago.js

## What does this MR do?
Replaces jQuery.timeago with [timeago.js](https://github.com/hustcc/timeago.js)

## Are there points in the code the reviewer needs to double check?

*  Check to make sure its working everywhere 😄 
*  Check to make sure the timeago wording matches what we have now (I think I've got this down but an extra pair of 👀 would help too)

## Why was this MR needed?

*  The jQuery.timeago version we have is outdated
*  timeago.js is smaller (7.19 KB => 4.52 KB)
* timeago.js has no jQuery dependency
* removes all inline javascript ⚔  for timeago
