Fix alignment issues after a fix on titles weight

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

## Commit title alignment fixed

**The fact that the first row has a smaller height than the other rows was not introduced by !2422 (I've checked by reverting 818607f0 on `master`).**

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**

        "tag": true,
        "sha": "d63117656af6ff57d99e50cc270f854691f335ad",

        "token": "9dd60b4f1a439d1765357446c1084c",
        "stage": "build",
        "project_id": 479,
        "project_name": "test",
        "artifacts_file": {
          "filename": "artifacts.zip",
          "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.

Allow access to artifacts for users with reporter role

Don't send (fake) email during dev bootstrap

This allows you to do:

    rake dev:setup BOOTSTRAP=1

and prevent dozens of letter_opener email popups in your browser.

In the latest GDK we automatically set BOOTSTRAP=1 during `make`.

Fix signup using kerberos

kerberos only provides a username and an email, but no name. Therefore a signup fails because the name is empty. Best guess for the name is probably the username, therefore use it as name.

I also created an issue for this: #5945

See merge request !2336

Consider that URL can end with '/' before redirecting.

Closes #7975

See merge request !2416

some OAuth providers (kerberos for example) only provide a username and an email, but no name. Therefore
a signup fails because the name is empty. Best guess for the name is
probably the username, therefore use it as name.
