Do not add the same icon multiple times to dropzones

Some DOM queries were to broad which caused paperclip icons and spinners
to be added multiple times to a dropzone in case of multiple dropzones
on a page.

![gitlab-dropzone-icon-bug](https://gitlab.com/dgerhardt/gitlab-ce/uploads/23e558a375cece21cc7af410e3839e05/gitlab-dropzone-icon-bug.png)

Steps to reproduce:
1. Open an existing issue or merge request with comments.
2. Move a file over the new comment dropzone. One paperclip icon should appear.
3. Now click the edit button for an existing comment and repeat step 2. You should see two paperclips.

Fixes #1725.

This should help for people who use scaling with retina or owners of MacBook Air laptops

Bump coveralls version, remove explicit rest-client dependency

coveralls got updated, so we don't need the rest-client entry in the Gemfile anymore.

Minor style fixes

### Reset ul list style types inside notes

Because notes are themselves `ul`s, lists inside of notes started at the wrong depth, so this resets that.

Closes #259

---

### Style all blockquote children, not just p

Makes styling of non-paragraph text, such as lists, inside blockquotes consistent.

Closes #1939

This reverts commit dd4fee5f.

Closes #259

Closes #1939

Note query information

The 'editable' field is required to be able to distinguish system-created notes from user comments. The 'upvote' and 'downvote' fields are so that endpoints don't need to duplicate GitLab's logic for what an up or downvote is.
