Properly check for a pre-existing error in `User#namespace_uniq`
Rails adds an empty error to the Errors object even if you just call
`#[]` on it:
```
[1] pry(main)> u = User.last
[2] pry(main)> u.errors.keys
=> []
[3] pry(main)> u.errors[:username].present?
=> false
[4] pry(main)> u.errors.keys
=> [:username]
```

Prior, if the user enabled 2FA, then disabled it and came back some time
after the grace period expired, they would be forced to enable 2FA
immediately.
Branded appearance to CE
Closes#11489
The difference with the EE version is only that there is no distinction between light and dark logos, though this wasn't used anyway. If this is fine, I'll create a MR on EE too.
TODO:
- [x] Copy docs
- [x] Make new screenshots
- [ ] Remove Custom Welcome message feature?
@rymai: I was unsure what labels to add to ping you, so I just ping you like this 😉

The only major difference with the EE version is the change from a light and dark logo to only a header logo
The dark logo wasn't used anyway, so it seemed to make sense to me to rename the field to the actual function of it

This ensures that the emptiness cache (used for Repository#empty? and
Repository#has_visible_content?) is flushed after comitting changes
(using the web editor, API or Git) for new repositories. Once a
repository is no longer empty there's no need to explicitly flush the
cache for Repository#empty?. The cache for
Repository#has_visible_content? in turn is already flushed whenever
needed.
Fixesgitlab-org/gitlab-ce#13387
Add a `Blob` model that wraps `Gitlab::Git::Blob`
This allows us to take advantage of Rails' `to_partial_path` to render
the correct partial based on the Blob type, rather than cluttering the
view with conditionals.
It also allows (and will allow in the future) better encapsulation for
Blob-related logic which makes sense for our Rails app but might not
make as much sense for the core `gitlab_git` library, such as detecting
if the blob is an SVG.

Fix missing ignored? for GenericCommitStatus
This is pretty important fix. We should not release 8.5 without this.
It critical error when handling GenericCommitStatus:
```
undefined method `ignored?' for #<GenericCommitStatus:0x007fe1a2a20fe0>
```
