Ensure Gravatar host looks like an actual host

Solves #10243.

I've chosen to simplify the method that extracts the host: since we
only need the host, let's get rid of the path and thus get rid of the
escaping problems!

Unit tests should ensure that most of the cases are covered.

When using IssuableFinder with a Group we can greatly reduce the amount
of projects operated on (due to not including all public/internal
projects) by simply passing it down to the ProjectsFinder class.

This reduces the timings of the involved queries from roughly 300
ms to roughly 20 ms.

Fixes gitlab-org/gitlab-ce#4071, gitlab-org/gitlab-ce#3707

Use a more sensible message for the AbuseReport uniqueness validation

Previously it was "user has already been taken", when really we were
saying the user has already been reported.

Fixes #9073

Issue page keeps jumping up

This happens when the discussion side is smaller than the sidebar and the sidebar will need to scroll. When this happens I calculate the height of the two and see if the discussion panel is smaller and make them the same height and add a class `no-affix` which makes the sidebar relative positioning so it won't stick to the top.

Fix alignment issues after a fix on titles weight

Fixes #8102. Fixes #3956. This fixes an alignment regression introduced by !2422. Sorry about that! :/

Let the CI runner know about builds that this build depends on

This allows us to implement artifacts passing: runner will download artifacts from all prior builds. It will happen automatically, and always, as long as artifacts are enabled.

## The changes:

This MR exposes list of prior builds in CI::API::Builds.

**The API response when asking for builds**

          "size": 0
        }
      }
    ]
  }
}
```

## How it will work?

**Example:**
```
build:
  type: build
  script:
  - echo TEST > test_file
  artifacts:
    untracked: true

rspec:
  type: test
  script:
  - test-my-project

staging:
  type: deploy
  script:
  - scp test_file root@server.com:
```

**The flow:**
1. We run `build`. The `build` creates a file `test_file`. This file gets archived and send us build artifacts.
2. We run `rspec`. The `rspec` downloads build artifacts from `build`. Uses the `test_file`.
3. We run `staging`. The `staging` downloads build artifacts from `build` and `rspec`, but since the `rspec` doesn't have build artifacts we skip that build. Deploys the `test_file`.

This partially implements the https://gitlab.com/gitlab-org/gitlab-ce/issues/3423.

In the next release we will introduce option to configure what artifacts are received.
