Fix #3758: Serious performance issues due to timeago()
being called n*(n+1)/2 times instead of n

See bug #3758 for a description. This merge request alters 
`time_ago_with_tooltip` to invoke the `timeago()` javascript on the
current timestamp only, instead of each one defined on the page so far.

Filter current user to top of assignee list in issues/merge requests

### What does this MR do?

Fixes #2076

Filter the current user to the top of the assignee list in issues and merge requests. This makes it fast/easy for a user to assign themselves without compromising the UI. This is the same thing we do in the filter select boxes in other places.

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

No.

### Why was this MR needed?

Users requested the feature in #2076

Update Docker Syntax

I think this documentation is using an out-of-date docker client. I guess that `-n` means `--name` (there is no `-n` in up-to-date docker) and `-l` means `--link` (`-l` is short for `--label` now).

Fix Error 500 when creating global milestones with Unicode characters

Two issues:

1. The constraints in the resources were incorrect. Here's what it was before:

```
group_milestone  GET /groups/:group_id/milestones/:id(.:format)  groups/milestones#show {:id=>/[a-zA-Z.0-9_\-]+(?<!\.atom)/, :group_id=>/[a-zA-Z.0-9_\-]+(?<!\.atom)/}
```

In this case, id is actually the title of the milestone, which can be anything at the moment.

After:
```
group_milestone  GET /groups/:group_id/milestones/:id(.:format)  groups/milestones#show {:id=>/[^\/]+/, :group_id=>/[a-zA-Z.0-9_\-]+(?<!\.atom)/}
```

2. `parameterize` would strip all Unicode characters, leaving a blank string. Rails would report something like:

```
ActionView::Template::Error (No route matches {:action=>"show", :controller=>"groups/milestones", :group_id=>#<Group id: 48, name: "ops-dev", path: "ops-dev", owner_id: nil, created_at: "2015-11-15 08:55:30", updated_at: "2015-12-02 06:23:26", type: "Group", description: "", avatar: "sha1.c71e73d51af1865c1bbbf6208e10044d46c9bb93.png", public: false>, :id=>"", :title=>"肯定不是中文的问题"} missing required keys: [:id]):
```

This change uses the babosa library to create a better slug, which surprisingly
isn't actually used by the global milestone controllers. Instead, they use the
title passed as a query string for some reason.

```

I have also added `once` to all `should_email` checks within `notification_service_spec.rb` since it's probably the correct behavior to notify users only once on the same event. Nothing else failed out of the box but we can keep these assertions for future.
