@rspeicher I'd love to get this into 8.1, since it's mostly refactoring/tweaking of stuff that was _introduced_ in 8.1.

9722 fix alignment of event items and its children

Allow groups to appear in the search results if the group owner allows it

https://dev.gitlab.org/gitlab/gitlabhq/issues/2565

See merge request !1751

Otherwise text will flow under the "timeago" element.
The original value was 80px (see commit 8b0906c8), but a value of 174px
makes more sense. (see event-title `calc` function).

update example of regex for pytest-cov

fixed typo in installation manual

Prevent the second, third, ... rows from having a different indentation
than the first commit row.

Adding the extra "15px padding" to the event item prevents this.
Having a 15px margin on the avatar only doesn't prevent this from
happening.

Add Facebook authentication

Try to avoid alignment issues as well.

Replace all usages of `git` command with configurable binary path

Closes #3311

See merge request !1742

On a tablet in portrait mode with a width of 768px the event-title isn't
aligned properly when the title contains a long string. This also
happens when resizing your browser viewport on a desktop.

Example string:
Administrator pushed new branch feature-branch-with-a-very-long-name at
Gitlab Org / Gitlab Test

In the UI it would look like the example below:

----------
|        |
| AVATAR |                                                                          less than a minute ago
|        |
----------
           Administrator pushed new branch feature-branch-with-a-very-long-name at...

Only redirect to homepage url when its not the root url

It was possible to create an infi redirect when the user set up the
`home_page_url` to redirect to the main URL of the gitlab instance.

This fix makes sure this redirect is not possible.

Remove duplicate orders

This changes the default order from `created_at DESC, id DESC` to just `id DESC` as this achieves the same results without the overhead of having to sort data twice (we've seen queries go from 200ms to just a few ms by removing the double sort).
