Automatically fork a project when not allowed to edit a file.
Fixes#3215.
To do:
- [ ] Add tests
-----
## "Edit" button on file in a project the user does NOT have write access to

## Clicking will automatically create a fork

## When the fork has been created, the user is returned to the edit page on the original project with a notice

## The user cannot change the target branch and is informed that editing will start an MR

## Hitting "Commit changes" will commit and start an MR from my fork to the origin project

-----
## "Create file, "Upload file" and "New directory" buttons in a project the user does NOT have write access to

## Clicking any of these options will automatically create a fork

## When the fork has been created, the user is returned to the tree page on the original project with a notice

## Clicking "New directory" again will show the modal. The user cannot change the target branch and is informed that editing will start an MR

## Hitting "Create directory" will commit and start an MR from my fork to the origin project

Confirmed this is issue still happens in GitLab 8.4, and it also happens on GitLab.com. Here's how to reproduce:
1. Login in a new browser.
2. Enter a search term on the top right that will land a hit in the "Issues" (e.g. GitLab).
3. Click on "Issues" tab. You should get an Error 500.
The issue is that @project isn't assigned to anything.

A limited number of pages have defined their own descriptions, but
otherwise we default to the Project's description (if `@project` is
set), or the old `brand_title` fallback.
The image will either be the uploaded project icon (never a generated
one), the user's uploaded icon or Gravatar, or, finally, the GitLab
logo.
