Added .closest() to find Reply button on click; fixes #401

This is to fix the issue where the icon-comment icon is clicked in the
Reply button of a note; the icon is used as the target and incorrectly
assumed to be the button itself, which causes the reply form to spawn
inside the button.
Add milestone descriptions on the group show page.
Use heading instead of strong and line breaks in description.
Update the tests with milestones descriptions.

Get Reply button as clicked target in notes.js.coffee

See issue #401

This is a small fix to properly find the reply button as the click target when an element inside the button is clicked (e.g. in this case, the ``<i class="icon-comment">`` element in the button, using the jQuery ``.closest(...)`` function.

Previously, the clicked element was assumed to be the button itself, which caused the comment form to spawn within the button when it was clicked (see the issue for screenshots & other details).
