Make diff file view easier to use on mobile screens

Viewing diffs on a mobile screen is a bit of an awkward experience at the moment. Here are a few issues (by no means complete):

## Before

### Tabs are scrunched

![image](https://gitlab.com/stanhu/gitlab-ce/uploads/45924e36cfb107dc56795a7dcdfbc5b5/image.png)

### Filenames take too much room, buttons cluttered

![image](https://gitlab.com/stanhu/gitlab-ce/uploads/a5e5611271fe26dfd3922aa0b8780458/image.png)

## After

This MR makes a few tweaks to make this a bit better. It just addresses a few issues, but there is plenty of room for improvement (e.g. shrink fonts, etc.):

### Eliminate padding to make tabs fit

### Make filenames, buttons more readable

This screenshot allows the filename to use the whole row, omits the file mode changes, and puts the buttons centered in the view:

Restore placeholders in issue filters from "Any" to "Milestone" and "Label"

1f11096c included new filters but made it hard to determine which dropdown did
what. This patch restores the original placeholders.

Normalize space-like characters in keys before output to gitlab-shell

gitlab-shell expects only one tab separator per key, and an SSH key with
a tab character in the comment, for example, would break things.

Closes #2970

Make the loading spinner toggle more explicit

Occasionally the loading spinner would stay visible after the tab
finished loading. This change makes the toggle explicit so that it's
always shown on `beforeSend`, and always hidden on `complete`.

Plus a bonus semi-colon eradication! 💥

Clarify support request message

Since we have the (GitLab.com) Support Forum, this message may be slightly confusing. Hopefully this wording improves understanding. If anyone has suggestions on making this clearer I'm open.

### Things to check

I'm not exactly loving the wording I have here. I'm open to improvements.

Fixed positioning of hamburger menu on header

Hey guys just noticed the hamburger menu for the top navigation was mis-aligned on 
`gitlab-ce:master` and `gitlab.com`.
I was not able to find an open issue or merge request directly referencing this issue so thought I would add a quick fix.

### Changes

This MR changes the vertical positioning from `top` to vertical margins (Like in bootstrap itself).
 - Also added a minor fix to remove `border-top` from the collapse menu so its the same height as the navigation.
 - finally added an active class to the hamburger toggle so you can see when its open.

This changes an element in `app/views/layouts/header/_default.html.haml` and thus would impact most pages behind login.

## Screenshots

Closes #2970

allow crawling of commit page but not patch/diffs

Fixes GDK issue where repos would not be imported properly

Seed-Fu runs this entire fixture in a transaction, so the `after_commit`
hook won't run until after the fixture is loaded. That is too late
since the Sidekiq::Testing block has already exited. Force clearing
the `after_commit` queue to ensure the job is run now.
