Disable colorization if STDOUT is not a tty

Closes #6118

Block the reported user before destroying the record

This is intended to prevent the user from creating new objects while the
transaction that removes them is being run, resulting in objects with
nil authors which can then not be edited.

Make sure time_ago_with_tooltip is using a Time object

Somehow this test existed on EE but not in CE, so it started failing
after a bad CE-to-EE merge.

Include the user_id in user_*_team system hooks.

Mention channel/key bug in irkerd docs

It patches core classes (such as String) to add colorization methods
like `red` which we can't disable the same way we can with the
Colorization gem.

Per this issue: https://gitlab.com/esr/irker/issues/2

A documentation update was added to irkerd (https://gitlab.com/esr/irker/commit/190808c37d4ab5f0f16fe35352ff36863c2732d5) but the bug is still there. Making a note of it here could save someone a lot of hassle. 

This could probably be worded better if someone else wants to take a stab at it.

Revert "Remove the `:coffee` and `:coffeescript` Haml filters"

This reverts commit ae7de2f8.

Several files in EE still use the `:coffeescript` filter and
I don't have time to fix them before the CE-to-EE merge.

See https://gitlab.com/gitlab-org/gitlab-ee/builds/553647

I will reintroduce this change in a future MR.

Improve admin area button style

A lot of the buttons in the top right in the admin area were too big. This makes those the new `btn-nr` size which seems to look nice.

Where a vew is called from doesn't matter as much. We already know what
action they belong to and this is more than enough information. By
removing the file/line number from the list of tags we should also be
able to reduce the number of series stored in InfluxDB.
