Fix event-title max-width in the dashboard

Include creator_id in project info of API

Revert "Preload lib/"

This reverts commit 5511a731.

The original commit added this because it also enabled threadsafety, a change which was itself later reverted in 66d6c809, but this got left behind.

I don't fully understand the reasoning behind it so if I'm wrong, please tell me.

My reasoning for reverting it is that it messes with Rails' (and by extension Spring's) class reloading during development. When I was working in `lib/gitlab/markdown` and had to stop and restart the server every time I made a change, I didn't know it at the time, but this was why. That was a huge pain point.

If it's needed for production perhaps we could add a `if Rails.env.production?` clause around it so that it doesn't mess with development.

Fix broken file browsing with a submodule that has a relative link

## What does this MR do?

This MR fixes an error that occurs when browsing a submodule with a relative link.

### Are there points in the code the reviewer needs to double check?

I re-wrote the function because I was confused by how the first one was supposed to work. Please review if it's clearer.

### Why was this MR needed?

A 500 Error would occur when using the file browser on a repo with a submodule. Here's how to reproduce the bug:

1. Start a new project in GitLab.
2. Clone git://git.gniibe.org/gnuk/gnuk.git/ locally.
3. Push repo to new project.
4. Click on "Files" in the project.

The .gitmodules file:
```
[submodule "chopstx"]
        path = chopstx
        url = ../../chopstx/chopstx.git
```

Move current user to the top of the list in author/assignee filter

### What does this MR do?

This MR puts the current user at the top of the user list in the author/assignee filters.

### Are there points in the code the reviewer needs to double check?

Is it best to do this in the JavaScript as it is in this MR, or are we better off adding an argument to the `/users` API to put the current user on top?

Also, I elected to put the current user after "Any" and "Unassigned"--it looked better. Do you agree?

### Why was this MR needed?

If you're trying to look for "Me" in the list, often you have to scroll down a long way to find yourself. Using the filter to find yourself is yet another step requiring the keyboard, and it's easy to forget that feature is available.

This option defaults to true in RedCarpet 3.2.0, but we handle
sanitization later in the process with html-pipeline.

Fix bug where Wiki pages that include a '/' were no longer accessible

### What does this MR do?

This MR fixes a regression that caused Wiki pages that included a '/' to no longer be accessible.

### Are there points in the code the reviewer needs to double check?

Are there cases that `wiki_helper.rb` doesn't handle?

### Why was this MR needed?

The upgrade from Rails v4.1.2 to v4.1.9 (76aad9b7) caused slashes in a model ID to be escaped automatically. We can no longer use the built-in the URL helpers to generate the links for Wiki pages if we want to maintain support for slashes. There is no option to tell the formatter otherwise:

Move project file links to tab bar.

The sidebar was getting awfully crowded, so I moved the file links to the tab bar alongside Activity and Readme. Unlike Readme, these files are not actually loaded in a tab, but simply link to the relevant blob, because we don't want to unnecessarily load the potentially large changelog or contribution guide on every project page load.
