Make Irker service check supported_events

63178a95 added the supported_events check for services. Since f84b7eef was just added, we should adjust it accordingly.

Implement merge requests search

It is same search like we have at issues page. It allows to quickly
filter merge requests based on title or desription. I copy-pasted some
js code from Issues.js. In future search (filtering) logic should be
refactoed into one class for merge requests and issues

Fix email images

## Dependencies:
This MR Depends on gitlab-org/html-pipeline-gitlab!4 being **merged and published** to rubygems.org

## What does this MR do?
This MR fixes the broken images in emails that occured scince we introduced access control for all attachments in 7.8.
The access control lead to broken images, because the user usually isn't logged into gitlab when opening the email in his mail client.
The solution to fix this, is to replace all images that were uploaded to gitlab as attachemnts with inline images in emails.

I only added one test for images in notes, because all notes share the same view. If it works fine for a note on a commit, then it'll also work the same for notes on a MR or on issues.

@DouweM can you review this please?

Closes #1161

Fix missing GitHub organisation repositories on import page.

Private repositories belonging to organizations rather than users can't be imported because `client.repos(org.login)` was requesting `/users/:org_login/repos` (which only returns public org repo's), while we need `/orgs/:org_login/repos` (which includes both public and private). The `client.org_repos` method does this.

cc @marin This is a bug in 7.8.x, but I'm not sure if it needs a minor release now or if it can go in 7.9.

Emoji cheatsheet fix

Worked through the help text for emoji to properly reference and use EmojiOne tags. Removed the ninja and reworked the first sentence a bit, as ninja isn't supported by EmojiOne. Should resolve ticket #953.
