Issuable filtering improvements
This improves the filtering of issues and merge requests by creating a single file that encapsulates all the filtering. Previously this was done with a file for issues and a file for merge requests.
Created the ability for the text search to be done alongside other filterables. Previously because this was outside the filterable form, this wasn't possible and would instead do either filter dropdown or text filter - not both. Fixes#4252
Fixed issue with not being able to filter and sort issues without refreshing the page. Fixes#15269

Fix concurrent request when updating build log in browser
If you have a slow internet connection the trace will not be updated correctly. We need to check if our request is the latest one.
Fixes: https://gitlab.com/gitlab-org/gitlab-ce/issues/17535

Clicking changes tab scrolls the window to show the content
When you click on the changes tab in a merge request, it will now scroll the window down to the content.

Issuable form due date
For some reason, this was never in the original merge request for due date?

Closes#15516

Fixed issue with enter key selecting wrong option in dropdown
If you search for a label and press enter the dropdown will select the last element rather than the first. This is because the currentIndex is -1 rather than 0

Remove broken inline runner description edit form
This remove inline form for editing runnner's description.
It is broken because of missing partial / incorrect response and it also does not make much sense, since we have under 'Edit' button a form that makes it possible to edit more than just a description.
See merge request !4095
Removes duplicates from the label dropdown
It concats the duplicate labels into a single label in the dropdown with the color being a gradient of the differnet colors being concatted.
I liked your idea @jschatz1 of using a standard icon color. However, with this i've taken all the duplicated colors & made a little gradient with them so it still half resembles the label colors (this has been limited to 4 or it could get crazy!)

Closes#16555, #14820

This button depends on Issue#can_be_worked_on? which in turn depends on
Issue#related_branches. By rendering this button asynchronously we can
finally remove all usages of Issue#related_branches and
Issue#referenced_merge_requests from the issues "show" page.
Add JS prefix to user tab classes
## What does this MR do
This MR adds the `js-` prefix to the classes which are used for js purposes only. This MR only affects the said classes inside `users/show.html.haml`.
## Are there points in the code the reviewer needs to double check?
I'm not entirely sure if this project uses the `js-` prefix for
classes that are used for js purposes only. Doing a grep shows some of the classes have the prefix, but I'm still unsure whether this project follows this rule.
## Why was this MR needed?
As I was working thru #13401, I wanted to add a tab on the user profile page to show the contributions outside the GitLab instance. Reading the JS, I came across this. This MR helps new people reading the code that the said classes are for js purposes only. Also, it helps the project work toward to uniform class naming.
I suggest that we document adding the `js-` prefix to classes for js purposes only (if this is the case for this project)
